Hmm, the SystemClock class should already be doing this. There is an 
update method which only retrieves the time from the kernel if we 
absolutely have to, and the EventLoop should already be doing this. I 
seem to recall Orion introduced this code around 3.5 years ago.

If SystemClock is not correctly caching its time value, that needs to be 
looked at.
