gmstrftime — Format a GMT/UTC time/date according to locale settings
gmstrftime ( string $format [, int|null $timestamp = null ] ) : string|false
Behaves the same as strftime() except that the time returned is Greenwich Mean Time (GMT). For example, when run in Eastern Standard Time (GMT -0500), the first line below prints "Dec 31 1998 20:00:00", while the second prints "Jan 01 1999 01:00:00".
format
See description in strftime().
timestamp
The optional timestamp parameter is an int Unix timestamp that defaults to the current local time if timestamp is omitted or null. In other words, it defaults to the value of time().
Returns a string formatted according to the given format string using the given timestamp or the current local time if no timestamp is given. Month and weekday names and other language dependent strings respect the current locale set with setlocale(). On failure, false is returned.
| Version | Description |
|---|---|
| 8.0.0 | timestamp is nullable now. |
