On RTC, I'd like a separate chip with an in package resonator (quartz or
MEMS) where the resonator and oscillator are well matched and temperature
compensated like the old Mostek MT48T02 TimeKeeper RAM. Further, I'd like
the chip to just be a 64 bit counter that advances once per second. I'll
use time.h to convert a Unix time stamp into whatever format I may need
for display. A Unix time stamp makes handling time zones easy. The RTC is
always UTC. Add an offset to get the time anywhere. Add another offset for
DST. Times are logged as the time stamp, taking much less space then a
bunch of BCD out of an RTC, and, with time.h, much easier to deal with.
