+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.
