-General
-=======
-
-+ It would be nice to utilize the interrupt capabilities of some
-  RTC parts.  This could be used to trigger checking the software
-  clock against the hardware clock.
-
-+ The periodic capability of most RTCs is not suitable for use
-  as a general purpose flexible clock tick source.  For example,
-  many RTCs generate only a handful of periods with 100 Hz being the
-  most frequent. 
-
-+ The tick field is not set on get.  Anything smaller than a second
-  is ignored on set and get operations.
-
-+ Day of week is ignored since RTEMS does not set it internally.
-
-+ There is no attempt in RTEMS to know about time zones.
-
-Harris ICM7170
-==============
-
-+ Tested on a DMV177.
-
-+ Interrupt capabilities are ignored.
-
-Mostek 48T08
-============
-
-+ Untested.
-
-+ NVRAM is ignored.

- *
- *    + two digit years 0-87 are mapped to 2000-2087.
- *    + two digit years 88-99 are mapped to 1988-1999.
