Timer Completion Flags can be force-set and force-reset.
Timer PVs cannot be force-set or force-reset, although the PVs can be
refreshed indirectly by force-setting/resetting the Completion Flag.
The accuracy of timers is different for Duplex CPU Systems than for Single
CPU Systems or CS1-H CPU Units.
