You have to get your time sync from somewhere.  One possibility you didnt
mention is TV.  Some stations (PBS?) broadcast clock information in the
vertical blank interval...  Since TV chips have been around for along
time, are well understood, and are *cheap*, this might be a reasonable
option.

I'm sure someone more knowledgable on this list could provide more
information.
