INT 1A,0 - Read System Clock Counter
AH = 00
on return:
AL = midnight flag, 1 if 24 hours passed since reset
CX = high order word of tick count
DX = low order word of tick count
- incremented approximately 18.206 times per second
- at midnight CX:DX is zero
- this function can be called in a program to assure the date is
updated after midnight; this will avoid the passing two midnights
date problem
