Return Values

CX	Creation time. The time is a packed 16-bit value with the following form:
	Bits	Contents
	0–4	Second divided by 2
	5–10	Minute (0–59)
	11–15	Hour (0–23 on a 24-hour clock)
DX	Creation date. The date is a packed 16-bit value with the following form:
	Bits	Contents
	0–4	Day of the month (1–31)
	5–8	Month (1 = January, 2 = February, and so on)
	9–15	Year offset from 1980 (that is, add 1980 to get the actual year)
SI	Number of 10 millisecond intervals in 2 seconds to add to the MS-DOS time. The number can be a value in the range of 0 to 199.

Otherwise, the function sets the carry flag and sets the AX register to an error value.
