Timezone conversion in php

Question

Can anyone suggest an easy method to convert date and time to different timezones in php?

Answer 1

You can use the datetime object or their function aliases for this:

Example (abridged from PHP Manual)

date_default_timezone_set('Europe/London');  $datetime = new DateTime('2008-08-03 12:35:23'); echo $datetime->format('Y-m-d H:i:s') . "\n"; $la_time = new DateTimeZone('America/Los_Angeles'); $datetime->setTimezone($la_time); echo $datetime->format('Y-m-d H:i:s');

Edit regarding comments

but i cannt use this method because i need to show date in different time zones as the user login from different locations

That's not a problem. When a user logs in, you determine his timezone and set it to your DateTime object just like shown. I'm using a similar approach in one of my projects and it works like a charm.

in the database i need to get the dates in any single timezone, then only it can be processed properly

You store the time either as a timestamp or a datetime in one timezone. When you query a DateTime field, you either convert the time in a DateTime object to this timezone or - if your db supports it - query with the selected timezone.
