Topic: Need a dynamic Javascript clock that shows UTC time under any circumstances (Page 1 of 1)

Hi guys I need some help here.. I need a javascript clock component that displays the correct UTC time no matter what the time on the client machine is. Any ideas on this?

If by correct you mean correct within the margin of error of trip from the server to the client, then it's pretty easy to inject the UTC timestamp into the JS served to the client. Which script will use the UTC timestamp ( assuming the clock of the server is not completetly off either, but that's unlikely ) as the basis to instanciate a Date object. Voilà.

To reduce the error, you can create the SCRIPT tag with the injected UTC timestamp dynamically. Right before append'ing it, create a Date object, and calculate the difference at the end of the dynamic script ( the one with the injected UTC timestamp ).

HTH,
