I need to generate a date in UTC format, but without the time part, that is, instead of getting:
Wed, 19 Jan 2021 19:27:00 GMT
I need only:
Wed, 19 Jan 2021
I know that there is a "long" way to do it by formatting the string myself using methods one instance of Date() and concatenating them. But I would like to know if there is a shorter way to do it.
By the way, I can only use Javascript vanilla.
I don't know what you mean by long but the code for extracting only the part you're looking for is pretty short.
'Wed, 19 Jan 2021 19:27:00 GMT'.split(' ').slice(0, -2)
Edit: If you really dislike this code I just found out that Date.toDateString() exists
By using substring:
let d = new Date();
d.toString().substring(0,15)

I wish to produce a date 30 days in the past using momentJS - it's pretty easy, I just use the following
const date30DaysPast = moment().utc().subtract(30, 'days').toDate(); // Sun Oct 29 2017 13:23:46 GMT+0100 (CET)
This is all great however I want the returned date to have no Time Zone or offset, I want the time to be GMT+0000 not as above GMT+0100 (CET) - for example:
Sun Oct 29 2017 13:23:46 GMT+0000
I wish to force this as I am using testing servers that are in different locations, and rather than take the time from the local browser I just want set a standard time. I thought using the utc method would do this for example should I write something like this in my test:
const oct4th2017 = moment.utc(new Date('October 04, 2017 11:13:00'));
the output is
Wed Oct 04 2017 09:13:00 GMT+0000
How can I remove the offset / time zone and set it to GMT on my original subtract method? I have tried wrapping in a parent utc method like so
const date30DaysPast = moment.utc(moment().utc().subtract(30, 'days').toDate());
but this doesn't work. I get the momentJS object.
Any advice could be appreciated, should my wording be bad or confusing please say so and I shall reword my question.
You already have your moment.js object without timezone. But the toDate() method creates a native Date object, which always has the local timezone (though it has various UTC methods).
Hello All, I have time in milliseconds and I want convert it into "dd/mm/yyyy hh:mm:ss"
I have tried the following code in javascript but I failed to do it, What I get is "Thu Jul 07 2016 16:22:10 GMT+0530 (IST)" this full timestamp, Code I tried is as follows:
self.users[i].lastLoggedIn = (new Date(self.users[i].lastLoggedIn)).toString("mm/dd/yyyy hh:mm:ss");
Where am I going wrong? for reference I have attached one screen shot of the same. Thank you..!!!
I suggest using moment.js for handling dates in Javascript. It is available for browsers, server-side engines and so on.
moment(self.users[i].lastLoggedIn).format("mm/dd/yyyy hh:mm:ss")
I have a date in the following format
Fri Mar 16 2012 05:53:18 GMT 0200 (GTB Standard Time)
And I want to convert it into a unix timestamp.
Until now I manually split the string by spaces and then I am giving it as an input to a Date object, in order to get milliseconds in a latter step.
Is there any easiest way?
(I am trying to avoid jQuery plug-ins and do it using vanila javascript)
Yes, the easiest way would be to pass the string to Date object and then call the getTime method:
var myDate = new Date('Fri Mar 16 2012 05:53:18 GMT+0200 (GTB Standard Time)');
console.log( myDate.getTime() ); //1331869998000
No need to split your string by spaces.
So now, its 9:23am. I have a UTC date string that represents the current date, that looks like this "2012-07-17T09:23:27.75"
I want that in a date object, so I can display a nicely formatted date, so I:
var myDate = new Date("2012-07-17T09:23:27.75")
// Gives --> Tue Jul 17 2012 10:23:27 GMT+0100 (GMT Daylight Time)
So because of daylight saving time I'm getting an hour-out issue. I can see that myDate.getTimezoneOffset() gives me -60, what's the standard / best practice way to get my date to actually reflect the current correct time? Have I just entered javascript date hell?
Try momentjs.com. I really found it handy for such things.
var myDate = moment("2012-07-17T09:23:27.75");
Gives you a date instance in your timezone (that basically configured on your computer). Moreover momentjs has nice human friendly formattings like "a couple of seconds ago", "a month ago",...
Dates are really a hell in JS (but not only in JS). The best thing you can do is to always only transport in UTC between browser <-> server. Then on the server convert it to what time format you like, you obviously only have to be consistent. That way I managed to handle date-times properly.
Try removing the 'T'
I was debugging some date time format issue in chrome when I found out that in console
new Date('2016-04-16T15:15:00') returns Sat Apr 16 2016 16:15:00 GMT+0100 (GMT Daylight Time)
while
new Date('2016-04-16 15:15:00') returns Sat Apr 16 2016 15:15:00 GMT+0100 (GMT Daylight Time)
In Javascript, how can I convert date/time in GMT to EST irrespective of user settings?
var tmpDate = New Date("enter any valid Date format here")
The javascript Date() function will automatically convert it to your local time.
Example:
var tmpDate = new Date("Fri Jul 21 02:00:00 GMT 2012");
alert(tmpDate);
//Result: Fri Jul 20 22:00:00 EDT 2012

i was surprise to find the simplest solution.
If you have date in GMT, and when you create date in browser it always create in that time zone.
Simplest way is create date object with GMT itself and then do below
starTime.setHours(starTime.getHours()+(starTime.getTimezoneOffset()/60));
That's it. Even if you have date of future after day light saving like after November then also it will also work.

all you have to do is get the time in miliseconds and then add the offset in milliseconds and then shift back to a date time object
