According to Kevin A. Foss:

Well the proposal in the GPC docs also adds a TimerValid field, just set that to False if the system doesn't support gettimeofday(), which is already checked for in rts-time.c.

Yes, that would be straightforward. Shouldn't the field better be called `us_TimerValid'? Peter Dipl.-Phys.
