Php sets the Beijing time function date_default_timezone_set ()

Set the Beijing time function date_default_timezone_set () in the php tutorial ()
Definition and usage
The date_default_timezone_set () function is used to set the default time zone of all date/time functions in the script.

Syntax
Date_default_timezone_set (timezone)

<? Php
$ Now = time ();
Date_default_timezone_set ('America/new york ');
Print date ('C', $ now );
Date_default_timezone_set ('Europe/paris ');
Print date ('C', $ now );
?>

Let's look at another example.

<? Php

Date_default_timezone_set ('America/denver ');

$ Summer = mktime );
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 datetime function has been rewritten), if the time zone does not comply with the rules, every call to the datetime function will generate an e_notice-level error message, if you use system settings or tz environment variables, information at the e_strict level will also be generated.
