GMDATE(3) 1 GMDATE(3) gmdate - Format a GMT/UTC date/time SYNOPSIS
string gmdate (string $format, [int $timestamp = time()]) DESCRIPTION
Identical to the date(3) function except that the time returned is Greenwich Mean Time (GMT). PARAMETERS
o $format - The format of the outputted date string. See the formatting options for the date(3) function. o $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(3). RETURN VALUES
Returns a formatted date string. If a non-numeric value is used for $timestamp, FALSE is returned and an E_WARNING level error is emitted. CHANGELOG
+--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 5.1.0 | | | | | | | The valid range of a timestamp is typically from | | | Fri, 13 Dec 1901 20:45:54 GMT to Tue, 19 Jan 2038 | | | 03:14:07 GMT. (These are the dates that corre- | | | spond to the minimum and maximum values for a | | | 32-bit signed integer). However, before PHP 5.1.0 | | | this range was limited from 01-01-1970 to | | | 19-01-2038 on some systems (e.g. Windows). | | | | | 5.1.1 | | | | | | | There are useful constants of standard date/time | | | formats that can be used to specify the $format | | | parameter. | | | | +--------+---------------------------------------------------+ EXAMPLES
Example #1 gmdate(3) example When run in Finland (GMT +0200), the first line below prints "Jan 01 1998 00:00:00", while the second prints "Dec 31 1997 22:00:00". <?php echo date("M d Y H:i:s", mktime(0, 0, 0, 1, 1, 1998)); echo gmdate("M d Y H:i:s", mktime(0, 0, 0, 1, 1, 1998)); ?> SEE ALSO
