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.
