    Detail:
      Most of the centisecond timers were incremented very early in the Timer0
      interrupt routine, but MetroGnome was incremented after we had called
      TickerV. Routines on TickerV are allowed to enable interrupts, so any
      interrupt routines that use OS_ReadMonotonicTime and IRQRQA are unable to
      accurately determine if the monotonic time is one tick out-of-date or not.
      MetroGnome is now incremented with the other timers.

      Tested with the timer code in STB-400 MPEGDriver.
