There is a timer based callback that is invoked every 1/60 of a second  
to grab the current millisecond clock to
update the low resolution msclock. This increases performance a few %  
since we avoid building ms from the nanosecond clock
1000+ times per second.

See MyTimerProc()
in sqMacTime.c

The SetupTimers() calls an ancient routine NewTimerUPP() to do this.  
That under os-x resolves to a timer thread firing every 1/60 of second.
I'm not sure yet where/what to change because this routine runs on a  
different pthread than ioShowDisplay()
