- *  This file interfaces with the real-time clock found in
- *  a Motorola MC146818A (common on PC hardware)
- *
- *  Year 2K Notes:
- *
- *  This chip only uses a two digit field to store the year.  This
- *  code uses the RTEMS Epoch as a pivot year.  This lets us map the
- *  two digit year field as follows:
- *
- *    + two digit years 0-87 are mapped to 2000-2087.
- *    + two digit years 88-99 are mapped to 1988-1999.
- *
- *  This is less than the time span supported by RTEMS.
