面向对象风格
<?php$winter = new DateTime('2010-12-21', new DateTimeZone('America/New_York'));$summer = new DateTime('2008-06-21', new DateTimeZone('America/New_York'));echo $winter->getOffset() . "\n";echo $summer->getOffset() . "\n";?>
过程化风格
<?php$winter = date_create('2010-12-21', timezone_open('America/New_York'));$summer = date_create('2008-06-21', timezone_open('America/New_York'));echo date_offset_get($winter) . "\n";echo date_offset_get($summer) . "\n";?>
以上例程会输出:
-18000 -14400
Note: -18000 = -5 hours, -14400 = -4 hours.
