8
+ It would be nice to utilize the interrupt capabilities of some
9
  RTC parts.  This could be used to trigger checking the software
10
  clock against the hardware clock.
11
 
12
+ The periodic capability of most RTCs is not suitable for use
13
  as a general purpose flexible clock tick source.  For example,
14
  many RTCs generate only a handful of periods with 100 Hz being the
15
  most frequent.
16
 
17
+ The tick field is not set on get.  Anything smaller than a second
18
  is ignored on set and get operations.
19
 
20
+ Day of week is ignored since RTEMS does not set it internally.
21
 
22
+ There is no attempt in RTEMS to know about time zones.
