gmstrftime — Format a GMT/UTC time/date according to locale settings
This function has been DEPRECATED as of PHP 8.1.0. Relying on this function is highly discouraged.
Alternatives to this function include:
$format, ?int $timestamp = null): string|falseBehaves 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".
This function depends on operating system locale information, which might be inconsistent with each other, or not available at all. Instead use the IntlDateFormatter::format() method.
formatSee 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.
