I am storing time in a MySQL database as a Unix timestamp and that gets sent to some JavaScript code. How would I get just the time out of it?
For example, in HH/MM/SS format.
let unix_timestamp = 1549312452
// Create a new JavaScript Date object based on the timestamp
// multiplied by 1000 so that the argument is in milliseconds, not seconds.
var date = new Date(unix_timestamp * 1000);
// Hours part from the timestamp
var hours = date.getHours();
// Minutes part from the timestamp
var minutes = "0" + date.getMinutes();
// Seconds part from the timestamp
var seconds = "0" + date.getSeconds();
// Will display time in 10:30:23 format
var formattedTime = hours + ':' + minutes.substr(-2) + ':' + seconds.substr(-2);
console.log(formattedTime);
For more information regarding the Date object, please refer to MDN or the ECMAScript 5 specification.
function timeConverter(UNIX_timestamp){
var a = new Date(UNIX_timestamp * 1000);
var months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'];
var year = a.getFullYear();
var month = months[a.getMonth()];
var date = a.getDate();
var hour = a.getHours();
var min = a.getMinutes();
var sec = a.getSeconds();
var time = date + ' ' + month + ' ' + year + ' ' + hour + ':' + min + ':' + sec ;
return time;
}
console.log(timeConverter(0));
JavaScript works in milliseconds, so you'll first have to convert the UNIX timestamp from seconds to milliseconds.
var date = new Date(UNIX_Timestamp * 1000);
// Manipulate JavaScript Date object here...
Use:
var s = new Date(1504095567183).toLocaleDateString("en-US")
console.log(s)
// expected output "8/30/2017"
and for time:
var s = new Date(1504095567183).toLocaleTimeString("en-US")
console.log(s)
// expected output "3:19:27 PM"
see Date.prototype.toLocaleDateString()
Modern Solution (for 2020)
In the new world, we should be moving towards the standard Intl JavaScript object, that has a handy DateTimeFormat constructor with .format() method:
function format_time(s) {
const dtFormat = new Intl.DateTimeFormat('en-GB', {
timeStyle: 'medium',
timeZone: 'UTC'
});
return dtFormat.format(new Date(s * 1e3));
}
console.log( format_time(12345) ); // "03:25:45"
Eternal Solution
But to be 100% compatible with all legacy JavaScript engines, here is the shortest one-liner solution to format seconds as hh:mm:ss:
function format_time(s) {
return new Date(s * 1e3).toISOString().slice(-13, -5);
}
console.log( format_time(12345) ); // "03:25:45"
Method Date.prototype.toISOString() returns time in
simplified extended ISO 8601 format, which is always 24 or 27 characters long (i.e. YYYY-MM-DDTHH:mm:ss.sssZ or
±YYYYYY-MM-DDTHH:mm:ss.sssZ respectively). The timezone is always
zero UTC offset.
This solution does not require any third-party libraries and is supported in all browsers and JavaScript engines.
I'm partial to Jacob Wright's Date.format() library, which implements JavaScript date formatting in the style of PHP's date() function.
new Date(unix_timestamp * 1000).format('h:i:s')
I'd think about using a library like momentjs.com, that makes this really simple:
Based on a Unix timestamp:
var timestamp = moment.unix(1293683278);
console.log( timestamp.format("HH/mm/ss") );
Based on a MySQL date string:
var now = moment("2010-10-10 12:03:15");
console.log( now.format("HH/mm/ss") );
shortest one-liner solution to format seconds as hh:mm:ss: variant:
console.log(new Date(1549312452 * 1000).toISOString().slice(0, 19).replace('T', ' '));
// "2019-02-04 20:34:12"
In moment you must use unix timestamp:
const dateTimeString = moment.unix(1466760005).format("DD-MM-YYYY HH:mm:ss");
This works with PHP timestamps
var d = 1541415288860;
//var d =val.timestamp;
//NB: use + before variable name
var date = new Date(+d);
console.log(d);
console.log(date.toDateString());
console.log(date.getFullYear());
console.log(date.getMinutes());
console.log(date.getSeconds());
console.log(date.getHours());
console.log(date.toLocaleTimeString());
var d =val.timestamp;
var date=new Date(+d); //NB: use + before variable name
console.log(d);
console.log(date.toDateString());
console.log(date.getFullYear());
console.log(date.getMinutes());
console.log(date.getSeconds());
console.log(date.getHours());
console.log(date.toLocaleTimeString());
the methods above will generate this results

There's a bunch of methods that work perfectly with timestamps. Cant list them all
UNIX timestamp is number of seconds since 00:00:00 UTC on January 1, 1970 (according to Wikipedia).
Argument of Date object in Javascript is number of miliseconds since 00:00:00 UTC on January 1, 1970 (according to W3Schools Javascript documentation).
See code below for example:
function tm(unix_tm) {
var dt = new Date(unix_tm*1000);
document.writeln(dt.getHours() + '/' + dt.getMinutes() + '/' + dt.getSeconds() + ' -- ' + dt + '<br>');
}
tm(60);
tm(86400);
gives:
1/1/0 -- Thu Jan 01 1970 01:01:00 GMT+0100 (Central European Standard Time)
1/0/0 -- Fri Jan 02 1970 01:00:00 GMT+0100 (Central European Standard Time)
Using Moment.js, you can get time and date like this:
var dateTimeString = moment(1439198499).format("DD-MM-YYYY HH:mm:ss");
And you can get only time using this:
var timeString = moment(1439198499).format("HH:mm:ss");
The problem with the aforementioned solutions is, that if hour, minute or second, has only one digit (i.e. 0-9), the time would be wrong, e.g. it could be 2:3:9, but it should rather be 02:03:09.
According to this page it seems to be a better solution to use Date's "toLocaleTimeString" method.
Another way - from an ISO 8601 date.
var timestamp = 1293683278;
var date = new Date(timestamp * 1000);
var iso = date.toISOString().match(/(\d{2}:\d{2}:\d{2})/)
alert(iso[1]);
Based on #shomrat's answer, here is a snippet that automatically writes datetime like this (a bit similar to StackOverflow's date for answers: answered Nov 6 '16 at 11:51):
today, 11:23
or
yersterday, 11:23
or (if different but same year than today)
6 Nov, 11:23
or (if another year than today)
6 Nov 2016, 11:23
function timeConverter(t) {
var a = new Date(t * 1000);
var today = new Date();
var yesterday = new Date(Date.now() - 86400000);
var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
var year = a.getFullYear();
var month = months[a.getMonth()];
var date = a.getDate();
var hour = a.getHours();
var min = a.getMinutes();
if (a.setHours(0,0,0,0) == today.setHours(0,0,0,0))
return 'today, ' + hour + ':' + min;
else if (a.setHours(0,0,0,0) == yesterday.setHours(0,0,0,0))
return 'yesterday, ' + hour + ':' + min;
else if (year == today.getFullYear())
return date + ' ' + month + ', ' + hour + ':' + min;
else
return date + ' ' + month + ' ' + year + ', ' + hour + ':' + min;
}
function getTIMESTAMP() {
var date = new Date();
var year = date.getFullYear();
var month = ("0" + (date.getMonth() + 1)).substr(-2);
var day = ("0" + date.getDate()).substr(-2);
var hour = ("0" + date.getHours()).substr(-2);
var minutes = ("0" + date.getMinutes()).substr(-2);
var seconds = ("0" + date.getSeconds()).substr(-2);
return year + "-" + month + "-" + day + " " + hour + ":" + minutes + ":" + seconds;
}
//2016-01-14 02:40:01
The modern solution that doesn't need a 40 KB library:
Intl.DateTimeFormat is the non-culturally imperialistic way to format a date/time.
// Setup once
var options = {
//weekday: 'long',
//month: 'short',
//year: 'numeric',
//day: 'numeric',
hour: 'numeric',
minute: 'numeric',
second: 'numeric'
},
intlDate = new Intl.DateTimeFormat( undefined, options );
// Reusable formatter
var timeStamp = 1412743273;
console.log( intlDate.format( new Date( 1000 * timeStamp ) ) );
Pay attention to the zero problem with some of the answers. For example, the timestamp 1439329773 would be mistakenly converted to 12/08/2015 0:49.
I would suggest on using the following to overcome this issue:
var timestamp = 1439329773; // replace your timestamp
var date = new Date(timestamp * 1000);
var formattedDate = ('0' + date.getDate()).slice(-2) + '/' + ('0' + (date.getMonth() + 1)).slice(-2) + '/' + date.getFullYear() + ' ' + ('0' + date.getHours()).slice(-2) + ':' + ('0' + date.getMinutes()).slice(-2);
console.log(formattedDate);
Now results in:
12/08/2015 00:49
There are multiple ways to convert unix timestamp to time (HH/MM/SS)
Using new Date() - this is in-built in javascript
moment package - this is a famous node module, but this is going to deprecate.
dayjs package - this is one of the latest and fast growing node module
Using new Date()
const dateTimeStr = new Date(1504052527183).toLocaleString()
const result = (dateTimeStr.split(", ")[1]).split(":").join("/")
console.log(result)
Using moment
const moment = require('moment')
const timestampObj = moment.unix(1504052527183);
const result = timestampObj.format("HH/mm/ss")
console.log(result);
Using day.js
const dayjs = require('dayjs')
const result = dayjs(1504052527183).format("HH/mm/ss")
console.log(result);
you can check the timestamp to time conversion with an online time conversion tool
// Format value as two digits 0 => 00, 1 => 01
function twoDigits(value) {
if(value < 10) {
return '0' + value;
}
return value;
}
var date = new Date(unix_timestamp*1000);
// display in format HH:MM:SS
var formattedTime = twoDigits(date.getHours())
+ ':' + twoDigits(date.getMinutes())
+ ':' + twoDigits(date.getSeconds());
function getDateTimeFromTimestamp(unixTimeStamp) {
let date = new Date(unixTimeStamp);
return ('0' + date.getDate()).slice(-2) + '/' + ('0' + (date.getMonth() + 1)).slice(-2) + '/' + date.getFullYear() + ' ' + ('0' + date.getHours()).slice(-2) + ':' + ('0' + date.getMinutes()).slice(-2);
}
const myTime = getDateTimeFromTimestamp(1435986900000);
console.log(myTime); // output 01/05/2000 11:00
You can use the following function to convert your timestamp to HH:MM:SS format :
var convertTime = function(timestamp, separator) {
var pad = function(input) {return input < 10 ? "0" + input : input;};
var date = timestamp ? new Date(timestamp * 1000) : new Date();
return [
pad(date.getHours()),
pad(date.getMinutes()),
pad(date.getSeconds())
].join(typeof separator !== 'undefined' ? separator : ':' );
}
Without passing a separator, it uses : as the (default) separator :
time = convertTime(1061351153); // --> OUTPUT = 05:45:53
If you want to use / as a separator, just pass it as the second parameter:
time = convertTime(920535115, '/'); // --> OUTPUT = 09/11/55
Demo
var convertTime = function(timestamp, separator) {
var pad = function(input) {return input < 10 ? "0" + input : input;};
var date = timestamp ? new Date(timestamp * 1000) : new Date();
return [
pad(date.getHours()),
pad(date.getMinutes()),
pad(date.getSeconds())
].join(typeof separator !== 'undefined' ? separator : ':' );
}
document.body.innerHTML = '<pre>' + JSON.stringify({
920535115 : convertTime(920535115, '/'),
1061351153 : convertTime(1061351153, ':'),
1435651350 : convertTime(1435651350, '-'),
1487938926 : convertTime(1487938926),
1555135551 : convertTime(1555135551, '.')
}, null, '\t') + '</pre>';

See Date/Epoch Converter.
You need to ParseInt, otherwise it wouldn't work:
if (!window.a)
window.a = new Date();
var mEpoch = parseInt(UNIX_timestamp);
if (mEpoch < 10000000000)
mEpoch *= 1000;
------
a.setTime(mEpoch);
var year = a.getFullYear();

If you want to convert Unix time duration to real hours, minutes, and seconds, you could use the following code:
var hours = Math.floor(timestamp / 60 / 60);
var minutes = Math.floor((timestamp - hours * 60 * 60) / 60);
var seconds = Math.floor(timestamp - hours * 60 * 60 - minutes * 60 );
var duration = hours + ':' + minutes + ':' + seconds;
Code below also provides 3-digit millisecs, ideal for console log prefixes:
const timeStrGet = date => {
const milliSecsStr = date.getMilliseconds().toString().padStart(3, '0') ;
return `${date.toLocaleTimeString('it-US')}.${milliSecsStr}`;
};
setInterval(() => console.log(timeStrGet(new Date())), 299);
I have a date string which coming from the db as follows
/Date(1469167371657)/
Is there any way to convert this date to following format using javascript
MM/DD/YYYY HH:MM
I've searched a lot but unble to find a solution
In plain javascript you have to write your own function for string format a date, for example for your string format:
var date = new Date(1469167371657);
function stringDate(date) {
var mm = date.getMonth()+1;
mm = (mm<10?"0"+mm:mm);
var dd = date.getDate();
dd = (dd<10?"0"+dd:dd);
var hh = date.getHours();
hh = (hh<10?"0"+hh:hh);
var min = date.getMinutes();
min = (min<10?"0"+min:min);
return mm+'/'+dd+'/'+date.getFullYear()+" "+hh+":"+min;
}
console.log(stringDate(date));
drier code version
var date = new Date(1469167371657);
function stringDate(date) {
return ("0" + (date.getMonth() + 1)).slice(-2)+'/'
+("0" + date.getDate()).slice(-2)+'/'
+date.getFullYear()+" "
+("0" + date.getHours()).slice(-2)+':'
+("0" + date.getMinutes()).slice(-2)
}
console.log(stringDate(date));
with pure js you can do the folowing
var d = new Date();
console.log(d.getMonth() + 1 + "/" + d.getDate() + "/" + d.getFullYear() + " " + d.getHours() + ":" + d.getMinutes())
You can use - http://momentjs.com/ and have it done like:
moment(1469167371657).format('MM/DD/YYYY HH:MM')
You can do this with the following steps:
1) convert the timestamp to a date object.
var timestamp = "/Date(1469167371657)/"; // However you want to save whatever comes from your database
timestamp = timestamp.substr(timestamp.indexOf("(")+1); // gives 1469167371657)/
timestamp = timestamp.substr(0,timestamp.indexOf(")")); // gives 1469167371657
var d = new Date(timestamp);
2) set it to your format
function leadZero(i) {if(i < 10) {return "0"+i;} return i;} // Simple function to convert 5 to 05 e.g.
var time = leadZero(d.getMonth()+1)+"/"+leadZero(d.getDate())+"/"+d.getFullYear()+" "+leadZero(d.getHours())+":"+leadZero(d.getMinutes());
alert(time);
Note: the date / timestamp you provided is too high for javascript to understand, so this example will not work correclty
I believe that number is milliseconds so to convert it to date, you would do this:
var time = new Date().getTime();
var date = new Date(time);
alert(date.toString()); // Wed Jan 12 2011 12:42:46 GMT-0800 (PST)
var time=1469167371657;
var date = new Date(time);
alert(date.toString());
What's the best way to convert date time formats using javascript?
I have this.. "2015-08-06T00:39:08Z"
and would like to change it to
"06/08/2015 12:39pm"
You could do it manually by instantiating a Date object:
var d = new Date('2015-08-06T00:39:08Z');
Then using the Date methods (like getDay or getUTCFullYear) to get the information needed and build the formatted string.
Or, if you don't mind relying on a library, you could use http://momentjs.com/ that provides a lot of methods, and particularly the format method: http://momentjs.com/docs/#/displaying/format/
// Example with moment.js
var formattedDate = moment('2015-08-06T00:39:08Z').format("MM/DD/YYYY hh:mma");
alert(formattedDate);
Use newDate() method, then Date Get Methods. Examples are explained on w3Schools
Method Description
getDate() Get the day as a number (1-31)
getDay() Get the weekday as a number (0-6)
getFullYear() Get the four digit year (yyyy)
getHours() Get the hour (0-23)
getMilliseconds() Get the milliseconds (0-999)
getMinutes() Get the minutes (0-59)
getMonth() Get the month (0-11)
getSeconds() Get the seconds (0-59)
getTime() Get the time (milliseconds since January 1, 1970)
With pure javascript:
code:
function formatDate(input) {
var datePart = input.match(/\d+/g),
year = datePart[0], // get only two digits
month = datePart[1],
day = datePart[2];
var h = parseInt(input.substr(input.indexOf("T") + 1, 2));
var m = parseInt(input.substr(input.indexOf(":") + 1, 2));
var dd = "AM";
if (h >= 12) {
h = hh - 12;
dd = "PM";
}
if (h == 0) {
h = 12;
}
m = m < 10 ? "0" + m : m;
alert(day + '/' + month + '/' + year + ' ' + h.toString() + ':' + m.toString() + dd);
}
formatDate('2015-08-06T00:39:08Z'); // "18/01/10"
I am using the HTML5 element datetime-local. I need to have two formats of the date. One as a date object the other as a string. I am going to store the date object in the database and I am going to use the string to set the datetime-local form input.
I need to convert this string to a date object:
"2014-06-22T16:01"
I can't seem to get the correct time. This is what I am getting. The time not correct.
Sun Jun 22 2014 09:01:00 GMT-0700 (PDT)
This is the how I am formating the date:
function formatTime(_date) {
var _this = this,
date = (_date) ? _date : new Date(),
day = date.getDate(),
month = date.getMonth() + 1,
year = date.getFullYear(),
hour = date.getHours(),
minute = date.getMinutes(),
seconds = date.getSeconds(),
function addZero(num) {
return num > 9 ? num : '0' + num;
}
minute = addZero(minute);
seconds = addZero(seconds);
hour = addZero(hour);
day = addZero(day);
month = addZero(month);
return year + '-' + month + '-' + day + 'T' + hour + ':' + minute;
};
Example:

If you are trying to get an ISO 8601 date string, you can try Date.prototype.toISOString. However, it always uses UTC. If you want to include the local timezone, use something like the following:
/* Return a string in ISO 8601 format with current timezone offset
** e.g. 2014-10-02T23:31:03+0800
** d is a Date object, or defaults to current Date if not supplied.
*/
function toLocalISOString(d) {
// Default to now if no date provided
d = d || new Date();
// Pad to two digits with leading zeros
function pad(n){
return (n<10?'0':'') + n;
}
// Pad to three digits with leading zeros
function padd(n){
return (n<100? '0' : '') + pad(n);
}
// Convert offset in mintues to +/-HHMM
// Note change of sign
// e.g. -600 => +1000, +330 => -0530
function minsToHHMM(n){
var sign = n<0? '-' : '+';
n = Math.abs(n);
var hh = pad(n/60 |0);
var mm = pad(n%60);
return sign + hh + mm;
}
var offset = minsToHHMM(d.getTimezoneOffset() * -1);
return d.getFullYear() + '-' + pad(d.getMonth() + 1) + '-' + pad(d.getDate()) +
'T' + pad(d.getHours()) + ':' + pad(d.getMinutes()) + ':' + pad(d.getSeconds()) +
'.' + padd(d.getMilliseconds()) + offset;
}
console.log(toLocalISOString(new Date())); // 2014-06-23T07:58:04.773+0800
Edit
The above probably misses your question, which seems to be;
I need to convert this string to a date object: "2014-06-22T16:01"
Presumaly you want to treat it as a local time string. ECMA-262 says that ISO–like strings without a timezone are to be treated as UTC, and that is what your host seems to be doing. So you need a function to create a local Date object from the string:
function parseYMDHM(s) {
var b = s.split(/\D+/);
return new Date(b[0], --b[1], b[2], b[3], b[4], b[5]||0, b[6]||0);
}
console.log(parseYMDHM('2014-06-22T16:01')); // Sun Jun 22 16:01:00 UTC+0800 2014
I have one input type text:
<input type="text" id="policyholder-dob" name="policyholder-dob" />
I want to type number in this field in mm/dd/yyyy format:
like 01/01/2014
This is my js code but its not working, what mistake have I made?
function dateFormatter(date) {
var formattedDate = date.getDate()
+ '/' + (date.getMonth() + 1) + '/' + date.getFullYear();
return formattedDate;
}
var nextduedate = $("#policyholder-dob").val();
var dateFormatDate = nextduedate.slice(0, 2);
var dateFormatMonth = nextduedate.slice(2, 4);
var dateFormatYear = nextduedate.slice(4, 8);
var totalFormat = dateFormatMonth + '/' + dateFormatDate + '/' + dateFormatYear;
var againNewDate = new Date(totalFormat);
againNewDate.setDate(againNewDate.getDate() + 1);
var todaydate = dateFormatter(againNewDate);
$("#policyholder-dob").prop("value", todaydate);
Any help will be really appreciated.
Thankfully, your input is consistently in this format:
mm/dd/yyyy
So you can convert it to a Date object through a custom function, such as:
function stringToDate(str){
var date = str.split("/"),
m = date[0],
d = date[1],
y = date[2],
temp = [];
temp.push(y,m,d);
return (new Date(temp.join("-"))).toUTCString();
}
Or:
function stringToDate(str){
var date = str.split("/"),
m = date[0],
d = date[1],
y = date[2];
return (new Date(y + "-" + m + "-" + d)).toUTCString();
}
Etc..
Calling it is easy:
stringToDate("12/27/1963");
And it will return the correct timestamp in GMT (so that your local timezone won't affect the date (EST -5, causing it to be 26th)):
Fri, 27 Dec 1963 00:00:00 GMT //Late december
Example
There are various ways to accomplish this, this is one of them.
I'd suggest moment.js for date manipulation. You're going to run into a world of hurt if you're trying to add 1 to month. What happens when the month is December and you end up with 13 as your month. Let a library handle all of that headache for you. And you can create your moment date with the string that you pull from the val. You substrings or parsing.
var d = moment('01/31/2014'); // creates a date of Jan 31st, 2014
var duration = moment.duration({'days' : 1}); // creates a duration object for 1 day
d.add(duration); // add duration to date
alert(d.format('MM/DD/YYYY')); // alerts 02/01/2014
Here's a fiddle showing it off.
