Bit 31-28 = Year-high*
Bit 27-24 = Month
Bit 23-21 = Year-low*
Bit 20-16 = Day
Bit 15 = Summertime flag**
Bit 12-8 = Hour
Bit 7 = Error flag***
Bit 6 = Reserved for future use***
Bit 5-0 = Minute
*The year is read by combining the
year-high and year-low field. For
example, year-high = 0010 and year-
low = 010 => year = 0010010
