In my application I have date coming in an ISO String format: '2020-12-20T15:21:28.411Z'
In the database the value is stored as: '2020-12-20 15:21:28+411'.
So how can I convert '2020-12-20T15:21:28.411Z' -> '2020-12-20 15:21:28+411'.
I don't want to use moment.js and .toLocaleString() does not work.
Assuming your date is in the string format, you can replace the dot with a + and the T with a space, then chop off the last character:
yourDate.replace(/\./g,"+").replace(/T/g," ").slice(0,-1)

I am trying to get specific format of datetime with time zone
i am getting string of time format which is shown below
var dateTime = "2020-06-01T01:50:57.000Z CDT"
I need to convert the format in to
const offsetTime = moment(date).add("-0.00", 'hours')
const formatedDate = moment(offsetTime, 'h:mm:ss A')
.utc()
.format('h:mm A')//(1:50 AM)
Required output
(1:50 AM CDT)
Do i need to split the string and get the format or do we have any method to convert it to this format in momentjs
In simple way to say
YYYY-MM-DDTHH:mm:ss.SSS[Z] z To hh:mm A z //format
and if the string contains only 2 character like "CT" instead of CDT how to capture that.
You can zz to get timezone in output. For ex:
moment()..format('h:mm A zz')
More documentation here momentJS
Use the moment-timezone to achieve this. Use the moment constructor to specify the input format, then specifying the required timezone. Finally use moment's format to get the required format
var dateTime = "2020-06-01T01:50:57.000Z CDT";
var timezone = "America/Chicago";
console.log(
moment(dateTime, "YYYY-MM-DD hh:mm:ss zz")
.tz(timezone)
.format("h:mm A zz")
);

Your date string is in ISO format with the 'Z' after seconds indicating that it is in UTC time. I am assuming that the 'CDT' is placed in the string in order to indicate which time zone this should be converted to. If you have control over how this string is represented then I recommend changing it so that you indicate the desired timezone elsewhere and simply store the date in UTC format. This way you can initialize a date or moment object with the ISO string as follows:
var date = moment("2020-06-01T01:50:57.000Z")
It is inconvenient the way it is currently since you cannot initialize it this way:
var date = moment("2020-06-01T01:50:57.000Z CDT")
The only option for handling the date in its current form is to parse it. You can do that like this:
var dateTime = "2020-06-01T01:50:57.000Z CDT"
var trimmed = dateTime.trim() // remove leading and trailing whitespace
var isoString = trimmed.substr(0, trimmed.indexOf(' '))
Which will produce the following string
2020-06-01T01:50:57.000Z
You can use that string I called "isoString" to initialize a date or moment object. The next obstacle is to handle converting that UTC string to a certain timezone (in this case CDT). It is simple if you want to convert the UTC date to the current users timezone since that will happen automatically when you initialize the moment or date object with the ISO date string. Otherwise, you need some way to get the timezone from 'CDT' into the format moment wants which was shown by #vjr12 ("America/Chicago"). The only way to do this is to either store that with the date string or create a mapping. It is much easier to convert from "America/Chicago" to "CDT" than it is to convert from "CDT" to "America/Chicago". Your only option with the current form is to create your own mapping from "CDT" to "America/Chicago". You could do something like:
let tzMap = new Map()
tzMap.set('CDT','America/Chicago')
// Set the rest of your timezones
You would need to do that for all timezones and then you could use the timezone parsed from your date string like this:
var tzAbbr = trimmed.substr(trimmed.indexOf(' ') + 1)
which will grab the "CDT" or "CT" for that matter. Then you could use your mapping like this:
var timezone = tzMap.get(tzAbbr)
timezone will be "America/Chicago" in this case and then you can use #vjr12 solution from here to get the form you want.
Note
I highly recommend that (if you are able) to change the current format of the datestring that you are using. The purpose of using UTC time is to be timezone agnostic so it does not make sense to store the timezone with the UTC string. If you want to preserve the timezone then you would be better off using a format which already embeds the timezone.
I have a string of Date and Time ("2017-11-29 11:08:43" YYYY-MM-DD hh:mm:ss) like this. I want to convert it into "29-11 11:08"(DD-MM hh:mm) format.
I tried it using below code. But not get any success. have you any solution?
convert: function (idleFrom) {
var date = Ext.Date.parse(idleFrom, "Y-m-d");
return date;
}
first change your string into date format using
var dt = new Date(idleFrom)
than change into you required format using
Ext.Date.format(dt, 'm/d/Y');
follw this link for more format
Hope it will work :)
If you have a string, and want it reformatted, you have to parse the string into a JS date object first, and then format the JS date object into the string representation you need:
var date = Ext.Date.parse("2017-11-29 11:08:43", "Y-m-d H:i:s")
var str = Ext.Date.format(date, "m/d/Y")
Please note that Ext.Date.parse is really picky regarding the format identifier. If the matching between the format identifier and the input string's format is not 100%, your date will be null.
E.g. Ext.Date.parse("2017-11-29 11:08:43", "Y-m-d H:i") will be null because the seconds are in the date string, but missing from the format identifier.
I have a SQL lookup a date that feeds into a field, but the date format contains time, I need to convert it to short date (mm/dd/yyyy). The MSSQL outputs this format (m/d/yyyy 12:00:00 AM) notice that the time is always '12:00:00 AM'. How do I remove the time?
$('#q60').change(function () {
var date = $('#q60 input').val(); //looking up the field that contains the date fed from SQL.
date = date.substring(0, date.indexOf(' '));
});
I have tried using split but while it output the correct thing it doesn't actually change the value in the field for some reason. I have also attempted using the .format similar to this post: Format a date string in javascript
But I am stuck!
with date = date.substring(0, date.indexOf(' ')); you're just storing splitted value in to date variable. to change the value of the input field add $('#q60 input').val(date) at the end of your function.
also in JS there's a whole Date object, with it you can format your date as you please. you can find more about it here and here
I have two inputs, a time and a date input. I'm trying to format them as an ISO string to send to the backend using moment.js.
This is what I have so far 01:00 2016-01-01, I need to format or convert that to ISO. Is there a way to do it using Moment?
To convert ISO I recommend the more standard
date.format();
or
JSON.stringify(yourDate)
or if you prefer momentjs:
var date = moment();
date.toISOString();
or
moment(yourDate).format('MM/DD/YYYY'); // <- your custom format string
To know what are the momentjs formatting rules start reading here
Assuming you are referring to ISO8601 and momentjs (2.10.6), I currently do it like this
var example = momentObject.format("YYYY-MM-DD[T]HH:mm:ss");
You need to use moment's parse function to first create the correct moment object from the data that you have (assuming a 24-hour clock, and month listed before the days):
var myMoment = moment("01:00 2016-01-01", "HH:mm YYYY-MM-DD");
Then you can use moment's format function to output the date in the ISO format that you want. Note that calling the format function without any parameters will output ISO 8601 by default:
myMoment.format();
See the moment docs for more info here.
Hope this helps!
We store every date data in ISO format using new Date().toISOString().
I tried to convert this ISO formatted date into Date object in node.js but I get Invalid Date response.
date string is isoDate = 2014-07-09T14:00:00.000Z
and I did console.log on Date.parse(isoDate); and new Date(isoDate);
but each returns NaN and Invalid Date.
I checked if the date string contains any invisible wrong character but they are fine and can be converted on browser console.
does this mean I need to convert the string manually and create Date object with parsed string?
Thanks for reading.
Try using moment library. It has a lot of functionality to work with dates and can easily be used both on client and server side. Calling moment("2014-07-09T14:00:00.000Z").toDate() would convert your string to a Date JavaScript Object, using this library.
I am posting this answer just in case somebody experience this like I did.
What happened to me is I thought I was sending an ISOString from the browser
{
startDate: date.startDate
}
which in fact I was sending a moment instance as parameter
When I checked in the network inspector I found out that the data being sent is in ISO format - yes, but it is enclosed in double quote ""
{
startDate: "2016-12-31T16:00:00.000Z"
}
it should not be enclosed in double qoutes and should look like this
{
startDate: 2016-12-31T16:00:00.000Z
}
what worked for me is to parse the moment to iso string
{
startDate: date.startDate.toISOString()
}
