OS_Word 14, with a reason code of 1, reads the time directly from the CMOS clock.
The time is returned in a Binary Coded Decimal (BCD) format.
OS_Word 14,1 is not Y2K compliant since it returns only a two-digit value for year. As such, this call is deprecated.
The year shall be returned as a BCD with a value within the range 0..99.
The range 0..65 should be assumed to be post 1999, and the range 66..99
to be pre 2000.
