To set the TOD clock in a SY/MAX controller first enter a value of "-1" into register 8108, then enter the new values into the remaining TOD clock registers (8109-8115). Finally to update and restart the TOD clock enter a value of "0" into 8108. The following table illustrates the SY/MAX TOD clock registers and their function:

REGISTER	FUNCTION	DECIMAL RANGE
8108	SET CLOCK	-1 (set), 0 (normal), 1(stop watch)
8109	Seconds	0-59

8113	Day of Month	1-31
