Best way to do a watch in javascript with server time synchronization
I'd like to make a js watch that:
-Start time is server time (the server will supply that in the page's source code).
-Updates every second.
-(preference, not obligatory) Compatible with the latest versions of gecko, webkit, presto and IE.

I have already checked many implementations of this but I wanted to know which one is the most efficient one. That is: the one that takes less resources from the PC and the one that is more precise among all the ones that exist.
