The date and time are stored in a four-register compressed format. Each of
the four registers, such as registers 1810 to 1813, contain a high and low byte
value to represent the date and time in hexadecimal. Table A–1 lists the
register and the portion of the date or time it represents.
For example, if the date was 01/25/00 at 11:06:59.122, the Hex value would
be 0119, 640B, 063B, 007A. Breaking it down into bytes we have the
following:
Table A–1:Date and Time Format
Register Hi Byte Lo Byte
Register 1 Month (1-12) Day (1-31)
Register 2 Year (0-199) Hour (0-23)
Register 3 Minute (0-59) Second (0-59)
Register 4 Milliseconds
