date - print the date SYNOPSIS
date [ option ] [ seconds ] DESCRIPTION
Print the date, in the format Tue Aug 16 17:03:52 CDT 1977 The options are -u Report Greenwich Mean Time (GMT) rather than local time. -n Report the date as the number of seconds since the epoch, 00:00:00 GMT, January 1, 1970. The conversion from Greenwich Mean Time to local time depends on the $timezone environment variable; see ctime(2). If the optional argument seconds is present, it is used as the time to convert rather than the real time. FILES
/env/timezone Current timezone name and adjustments. /adm/timezone A directory containing timezone tables. /adm/timezone/local Default timezone file, copied by init(8) into /env/timezone. SOURCE
/sys/src/cmd/date.c DATE(1)

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

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.'; } ?> CHANGELOG
+--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 5.3.0 | | | | | | | Now throws E_WARNING rather than E_STRICT. | | | | | 5.1.2 | | | | | | | The function started to validate the $time- | | | zone_identifier parameter. | | | | +--------+---------------------------------------------------+ SEE ALSO
