# PHP Function gmdate()

## Syntax

string gmdate ( string $format [, int $timestamp] );

## Definition and Usage

This is identical to the date() function except that the time returned is Greenwich Mean Time (GMT).

## Paramters

Parameter | Description
--- | ---
format | Required. The format of the outputted date string. See the formatting options for the date() function.
timestamp | Optional. This 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 Value

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.

## Example

Following is the usage of this function:

    <?php
    echo date("M d Y H:i:s", mktime(0, 0, 0, 1, 1, 2007));
    echo gmdate("M d Y H:i:s", mktime(0, 0, 0, 1, 1, 2007));
    ?>

This will produce following result:

    Jan 01 2007 00:00:00
    Jan 01 2007 07:00:00
