You are actually wanting to sync it, and it is in the same method as the gl_realtime... The only difference is that the checking of the servers time isn't needed, but what does need to be is a variable set which is hour/min/seconds, and simply count the time at a relative speed.

Here's something that may assist you, as I have also used it in the past.
