Question

I get a timestamp from mysql like

2012-04-12 16:42:33

in PHP how can i subtract hours, or basically how can i change timezone (-3 hours)?

Answer 1

You should use PHP’s DateTime. You can check out the supported formats and then create a new object:

$date=new DateTime("2012-04-12 16:42:33");

This object also supports changing timezones and other conversions. Setting a new timezone (from PHP manual):

$date->setTimezone(new DateTimeZone('Pacific/Chatham'));
