INT 21 - DOS 1+ - GET SYSTEM TIME                                               
	AH = 2Ch
Return: CH = hour
	CL = minute
	DH = second
	DL = 1/100 seconds
Note:	on most systems, the resolution of the system clock is about 5/100sec,
	  so returned times generally do not increment by 1
	on some systems, DL may always return 00h
