# # $Id$ # 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.
