	;BOSKNOP's CODE

	;Awaits duetime, then returns to the caller (like some sort of "sleep until duetime").
	;If the computer is in hibernate or suspend mode
	;at duetime, it will be reactivated (hardware support provided)
	;Parameters: Year, Month, Day, Hour, Minute together produce duetime
	;Hibernate: If Hibernate=1, the function hibernates the computer. If Hibernate=2 the computer is set to
	;         suspend-mode
	;Resume: If Resume=1, the system is restored from power save mode at due time
	;Name: Arbitrary name for the timer
