PHP Tutorial Set the Date_default_timezone_set function ()
Definition and usage
The Date_default_timezone_set () function sets the default time zone for all date/time functions used in the script.

Date_default_timezone_set (TimeZone)

$now = time ();
Date_default_timezone_set (' america/new York ');
Print date (' C ', $now);
Date_default_timezone_set (' Europe/paris ');
Print date (' C ', $now);

Look at one more example.

Date_default_timezone_set (' America/denver ');

$summer = Mktime (12,0,0,7,4,2008);
Print date (' C ', $summer). "N";

Date_default_timezone_set (' America/phoenix ');
Print date (' C ', $summer). "N";

Note: since PHP 5.1.0 (This version of the date time function is rewritten), if the time zone is not a rule, each call to a DateTime function produces an E_notice level error message, and the e_strict level of information is generated if the system setting or the TZ environment variable is used.
