These jQuery world clocks are easy to implement, easy to skin, and only require you to add 5 lines of code to your PHP. You can add as many clocks in as many timezones as you like. You can keep them in a grid or place them throughout your page as needed.
These clocks take into consideration daylight savings time, even in India (30 daylight savings offset) and Nepal (45 minute offset). They use server time, rather than local, so they’ll be correct whether the users’ time is correct or not.
The second hand is optional and you can choose between smooth rotation and a ticking clock.
