I'm trying to display the timecreated in a date format using javascript but I can't seem to find any documentation about it online...
If anyone knows how to do that would help a lot!
If timecreated is a Unix timestamp, you can use
var date = new Date(timecreated * 1000);
because a unix timestamp is the number of seconds since 1970. If not, it might be enough to just put new Date(timecreated)
There is the following code:
console.log(order.start_time);
console.log(moment(order.start_time).format("HH:MM"));
I just want to get hour and minute from date using moment and display it. Output:
2014-06-30T09:00:00.000Z
13:06
But I don't understand why my date is formatted incorrectly. Thanks in advance.
Please note that there is a difference between MM and mm. The first formatting option is used for months, while the second is for days.
More information here: http://momentjs.com/docs/#/parsing/string-format/
From the doc here:
http://momentjs.com/docs/#/displaying/format/
You should use HH:mm. Then your time will have right format.
Further information, the time might be incorrectly as you expected because timezone. Momentjs auto display time in your system timezone.
Update:
To display time in specified Timezone, use "zone" method:
console.log(moment(order.start_time).zone('+00').format("HH:mm"));
Using Moment.js I can't transform a correct moment object to a date object with timezones. I can't get the correct date.
Example:
var oldDate = new Date(),
momentObj = moment(oldDate).tz("MST7MDT"),
newDate = momentObj.toDate();
console.log("start date " + oldDate)
console.log("Format from moment with offset " + momentObj.format())
console.log("Format from moment without offset " + momentObj.utc().format())
console.log("(Date object) Time with offset " + newDate)
console.log("(Date object) Time without offset "+ moment.utc(newDate).toDate())
Use this to transform a moment object into a date object:
From http://momentjs.com/docs/#/displaying/as-javascript-date/
moment().toDate();
Yields:
Tue Nov 04 2014 14:04:01 GMT-0600 (CST)
As long as you have initialized moment-timezone with the data for the zones you want, your code works as expected.
You are correctly converting the moment to the time zone, which is reflected in the second line of output from momentObj.format().
Switching to UTC doesn't just drop the offset, it changes back to the UTC time zone. If you're going to do that, you don't need the original .tz() call at all. You could just do moment.utc().
Perhaps you are just trying to change the output format string? If so, just specify the parameters you want to the format method:
momentObj.format("YYYY-MM-DD HH:mm:ss")
Regarding the last to lines of your code - when you go back to a Date object using toDate(), you are giving up the behavior of moment.js and going back to JavaScript's behavior. A JavaScript Date object will always be printed in the local time zone of the computer it's running on. There's nothing moment.js can do about that.
A couple of other little things:
While the moment constructor can take a Date, it is usually best to not use one. For "now", don't use moment(new Date()). Instead, just use moment(). Both will work but it's unnecessarily redundant. If you are parsing from a string, pass that string directly into moment. Don't try to parse it to a Date first. You will find moment's parser to be much more reliable.
Time Zones like MST7MDT are there for backwards compatibility reasons. They stem from POSIX style time zones, and only a few of them are in the TZDB data. Unless absolutely necessary, you should use a key such as America/Denver.
.toDate did not really work for me, So, Here is what i did :
futureStartAtDate = new Date(moment().locale("en").add(1, 'd').format("MMM DD, YYYY HH:MM"))
hope this helps
Since momentjs has no control over javascript date object I found a work around to this.
const currentTime = new Date();
const convertTime = moment(currentTime).tz(timezone).format("YYYY-MM-DD HH:mm:ss");
const convertTimeObject = new Date(convertTime);
This will give you a javascript date object with the converted time
The question is a little obscure. I ll do my best to explain this. First you should understand how to use moment-timezone. According to this answer here TypeError: moment().tz is not a function, you have to import moment from moment-timezone instead of the default moment (ofcourse you will have to npm install moment-timezone first!). For the sake of clarity,
const moment=require('moment-timezone')//import from moment-timezone
Now in order to use the timezone feature, use moment.tz("date_string/moment()","time_zone") (visit https://momentjs.com/timezone/ for more details). This function will return a moment object with a particular time zone. For the sake of clarity,
var newYork= moment.tz("2014-06-01 12:00", "America/New_York");/*this code will consider NewYork as the timezone.*/
Now when you try to convert newYork (the moment object) with moment's toDate() (ISO 8601 format conversion) you will get the time of Greenwich,UK. For more details, go through this article https://www.nhc.noaa.gov/aboututc.shtml, about UTC. However if you just want your local time in this format (New York time, according to this example), just add the method .utc(true) ,with the arg true, to your moment object. For the sake of clarity,
newYork.toDate()//will give you the Greenwich ,UK, time.
newYork.utc(true).toDate()//will give you the local time. according to the moment.tz method arg we specified above, it is 12:00.you can ofcourse change this by using moment()
In short, moment.tz considers the time zone you specify and compares your local time with the time in Greenwich to give you a result. I hope this was useful.
To convert any date, for example utc:
moment( moment().utc().format( "YYYY-MM-DD HH:mm:ss" )).toDate()
let dateVar = moment('any date value');
let newDateVar = dateVar.utc().format();
nice and clean!!!!
I needed to have timezone information in my date string. I was originally using moment.tz(dateStr, 'America/New_York').toString(); but then I started getting errors about feeding that string back into moment.
I tried the moment.tz(dateStr, 'America/New_York').toDate(); but then I lost timezone information which I needed.
The only solution that returned a usable date string with timezone that could be fed back into moment was moment.tz(dateStr, 'America/New_York').format();
try (without format step)
new Date(moment())
var d = moment.tz("2019-04-15 12:00", "America/New_York");
console.log( new Date(d) );
console.log( new Date(moment()) );

moment has updated the js lib as of 06/2018.
var newYork = moment.tz("2014-06-01 12:00", "America/New_York");
var losAngeles = newYork.clone().tz("America/Los_Angeles");
var london = newYork.clone().tz("Europe/London");
newYork.format(); // 2014-06-01T12:00:00-04:00
losAngeles.format(); // 2014-06-01T09:00:00-07:00
london.format(); // 2014-06-01T17:00:00+01:00
if you have freedom to use Angular5+, then better use datePipe feature there than the timezone function here. I have to use moment.js because my project limits to Angular2 only.
new Date(moment()) - could give error while exporting the data column in excel
use
moment.toDate() - doesn't give error or make exported file corrupt
i am working on javascript. and i have time in milliseconds. so i have to display the time in PST time Zone. i have tried for GMT. but is there any option to display the time in PST format in which the input is in milliseconds like 1671673550214. so iam trying to convert this milliseconds to time and date format of PST. same as the below code does. pleas help.
Here is my tried code:
var time = new Date().getTime();
var date = new Date(time);
document.write(date.toString());
i have even tried of using UTCString(), UTC() and toString(); but things is getting converted to GMT and not to PST.
Please check this library, it has lot of functions to display and manupilate date time.
http://momentjs.com/
http://momentjs.com/docs/
Also please check following post
Moment.js: Format date in a specific timezone\
If you dont want to use external lib, see the following article
http://www.techrepublic.com/article/convert-the-local-time-to-another-time-zone-with-this-javascript/6016329
You can use timezonjs which help you to convert the time to any timezone.

I got this problem when dealing with date time conversion. I have timestamp data from postgreSQL database with format like this one
"2011-04-04 19:27:39.92034"
In order to display it in highcharts, I have to convert it to date or time object. Without milliseconds, I easily convert it with Date.js
But milliseconds can't be handled with that library. I tried also with Date.parse but always got NaN.
Any solution for this problem? Thank you
JS built in Date class should be able to handle this, and getTime() can return milliseconds since start 1970 (UNIX time). Watch out for time zone issues though; the constructor may interpret the date/time as being local, but getTime()'s milliseconds since 1970 may be in UTC, baking in a conversion that is difficult to remove.
new Date("2011-04-04 19:27:39.92034").getTime()
1301941659920
Many ways to Rome. The given code will return '(datestr=) 2011-4-4 19:27:39.92'. Is that what you look for?
var darr = '2011-04-04 19:27:39.92034'.split('.')
, dat=new Date(darr[0])
, datestr = '';
dat.setMilliseconds(Math.round(darr[1]/1000));
datestr = [ [dat.getFullYear(),dat.getMonth()+1,dat.getDate()].join('-')
,' ',
[dat.getHours(),dat.getMinutes(),dat.getSeconds()].join(':')
,'.',
dat.getMilliseconds()
].join('');
Can't you just cut of the last 6 chars of that string? You might then round the miliseconds and eventually add a second to you time object.
This is simpler and in one line:
new Date('01/09/2015 06:16:14.123'.split(".")[0])
