Notes:         The system timer is the timer set when the system is
started. This date is temporary, lasting only as
long as the system is turned on.

This service is available only for XTs dated 1/10/86
and later. ATs and XT-286s will set the Carry Flag,
thus reporting an error state. Previous machines
will report unpredictable results (including the
state of the Carry Flag).
