Syntax
dateObj.toUTCString()
Return value
A string representing the given date using the UTC time zone.
Description
The value returned by toUTCString()
is a string in the form
Www, dd Mmm yyyy hh:mm:ss GMT
where:
Www | Day of week, as three letters (e.g. Sun, Mon, ...) |
dd | Day of month, as two digits with leading zero if required |
Mmm | Month, as three letters (e.g. Jan, Feb, ...) |
yyyy | Year, as four or more digits with leading zeroes if required |
hh | Hour, as two digits with leading zero if required |
mm | Minute, as two digits with leading zero if required |
ss | Seconds, as two digits with leading zero if required |
Prior to ECMAScript 2018, the format of the return value varied according to the platform. The most common return value was an RFC-1123 formatted date stamp, which is a slightly updated version of RFC-822 date stamps.
Examples
Using toUTCString()
var today = new Date('Wed, 14 Jun 2017 00:00:00 PDT'); var UTCstring = today.toUTCString(); // Wed, 14 Jun 2017 07:00:00 GMT
