LEARN ABOUT PHP

date_default_timezone_set

DATE_DEFAULT_TIMEZONE_SET(3)						 1					      DATE_DEFAULT_TIMEZONE_SET(3)

date_default_timezone_set - Sets the default timezone used by all date/time functions in a script

SYNOPSIS

       bool date_default_timezone_set (string  $timezone_identifier)

DESCRIPTION

       date_default_timezone_set(3) sets the default timezone used by all date/time functions.

       Note

	       Since  PHP  5.1.0 (when the date/time functions were rewritten), every call to a date/time function will generate a E_NOTICE if the
	      timezone isn't valid, and/or a E_WARNING message if using the system settings or the $TZ environment variable.

	Instead of using this function to set the default timezone in your script, you can also use the  INI  setting  date.timezone  to  set  the
       default timezone.

PARAMETERS

	      o $timezone_identifier
		-  The	timezone identifier, like UTC or Europe/Lisbon. The list of valid identifiers is available in the "List of Supported Time-
		zones".

RETURN VALUES

	This function returns FALSE if the $timezone_identifier isn't valid, or TRUE otherwise.

EXAMPLES

       Example #1

	      Getting the default timezone

	      <?php
	      date_default_timezone_set('America/Los_Angeles');

	      $script_tz = date_default_timezone_get();

	      if (strcmp($script_tz, ini_get('date.timezone'))){
		  echo 'Script timezone differs from ini-set timezone.';
	      } else {
		  echo 'Script timezone and ini-set timezone match.';
	      }
	      ?>
