Set (write) the real time clock.
Do Not Write more than once per minute
To write the real time clock, the system
variables (SetMonth, SetDay, SetYear,
SetHour, SetMinute, SetSecond,
SetWeekday) must first be loaded with the
correct date and time. Then, a 1 must be
written to the state portion of this system
variable to write the new date and time to
the system clock.
0 = no action
1 = set/write the clock
