PHP | gmstrftime() Function Last Updated : 31 Aug, 2018 Comments Improve Suggest changes Like Article Like Report The gmstrftime() function is an inbuilt function in PHP which is used to format a GMT/UTC time/date according to local settings. The gmstrftime() function in PHP behaves in the same way as strftime() except that the time returned by the gmstrftime() function is Greenwich Mean Time (GMT). The $format and $timezone are sent as parameters to the gmstrftime() function and returns a string formatted according to the format specified using the given timestamp. Syntax: string gmstrftime( $format, $timestamp ) Parameters: This function accepts two parameters as mentioned above and described below: $format: It is a mandatory parameter which is used to specify the format of result. $timestamp: It is an optional parameter which is used to specify the UNIX timestamp that represents the date and/or time to be formatted. Return Value: This function returns a formatted string according to the format specified by the given timestamp. Exceptions: Month, weekday names and other language-dependent strings respect the current locale set with setlocale() function. If a timestamp is not given in the gmstrftime() function, it defaults to the value of time() or in other words to the current local time.
