# gmstrftime

(PHP 4, PHP 5)

gmstrftime — Format a GMT/UTC time/date according to locale settings

### Description

string gmstrftime ( string `$format` [, int `$timestamp` ] )

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".

### Parameters

`format`

  See description in strftime().

`timestamp`

  The optional `timestamp` parameter is an integer Unix timestamp that defaults to the current local time if a `timestamp` is not given. In other words, it defaults to the value of time().

### Return Values

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().

### Examples

Example#1 gmstrftime() example

`<?php
setlocale(LC_TIME, 'en_US');
echo strftime("%b %d %Y %H:%M:%S", mktime(20, 0, 0, 12, 31, 98)) . "\n";
echo gmstrftime("%b %d %Y %H:%M:%S", mktime(20, 0, 0, 12, 31, 98)) . "\n";
?>`
