'Worldclock(s) PHP/JS [duplicate]

Timezone conversion in php

Looking for a script to display a number of different time (zones) on a site - flash can do this but has become obsolete due to Apple and the JavaScript I have found all miss the daylight savings adjustment functionality.

Script/plugin needs to be un-styled for site branding purposes. Site = PHP

This may seem a dumb answer, but what's wrong with calculating them yourself? Shouldn't all timezones be off from the previous by exactly one hour? Daylight savings time is the same - add or remove one hour, unless I'm missing something vital here :)

Of course if you need to display the timezone by city, it would be quite a hassle.
