After all the issues seen after the last rollover, I'd think receivers
would have been made robust against this.
One obvious method would be to keep a checkpoint date (or 1024 week
cycle # + week offset) in EEPROM. To avoid issues with using up EEPROM
r/w cycles, only update it anytime the currently received date is more
than a year beyond the currently stored date.
