How can I parse a simple date string and let JavaScript know that it's actually a UTC date? Currently, if I do new Date('2015-08-27')
it converts it to my timezone.
To convert a JavaScript date object to a UTC string, you can use the toUTCString() method of the Date object. The toUTCString() method converts a date to a string, using the universal time zone. Alternatively, you could also use the Date. UTC() method to create a new Date object directly in UTC time zone.
Browsers may differ, however, Date. getTime() returns the number of milliseconds since 1970-01-01. If you create a new Date using this number, ex: new Date(Date. getTime()); it will be UTC, however when you display it (ex: through the chrome dev tools console) it will appear to be your local timezone.
The Date. UTC() method in JavaScript is used to return the number of milliseconds in a Date object since January 1, 1970, 00:00:00, universal time. The UTC() method differs from the Date constructor in two ways: Date.
JavaScript Date toUTCString() The toUTCString() method returns a date object as a string, according to UTC. Tip: The Universal Coordinated Time (UTC) is the time set by the World Time Standard. Note: UTC time is the same as GMT time.
You can do append 'T00:00:00.000Z'
to make the time zone specific (Z
indicates UTC)
new Date('2015-08-27' + 'T00:00:00.000Z')
Note that new Date('2015-08-27')
is treated differently in ES5 (UTC) vs. ES6 (Local), so you can't expect it any correction to be work consistently if you were planning to to hard code it (i.e. don't do it)
Also, do note that your console.log
might show you the local time corresponding to the UTC time the expression evaluates to (that tends to throw you off a bit if you are expecting UTC to be at the end for expression that evaluate to UTC times and your local time zone at the end for those that evaluate to your local time). For instance
new Date('2015-08-27T00:00:00.000Z')
could show
Thu Aug 27 2015 1:00:00 GMT+100
which is the same as
Thu Aug 27 2015 00:00:00 UTC
