INT 1A - TIME - SET REAL-TIME CLOCK TIME (AT,XT286,PS)

	AH = 03h
	CH = hour (BCD)
	CL = minutes (BCD)
	DH = seconds (BCD)
	DL = daylight savings flag (00h standard time, 01h daylight time)
Return: nothing
Note:	this function is also supported by the Sperry PC, which predates the
	  IBM AT; the data is specified in binary rather than BCD on the
	  Sperry, and the value of DL is ignored
