/* 
* Modified version of [[User:AzaToth/liveclock.js]]
* This version has a feature that makes it, at most, only a few milliseconds ahead of the actual time.
*
* Yes, a few hundred milliseconds (the normal margin of error for these clocks) doesn't really make that much of a difference, 
* but I'm just that anal.
