Sorry Glenn, I totally do not get your query.
Rockbox-Devices with RTC (real time clock) do always know the exact
date and time except if the batteries have gone totally low or have
been replaced. In both cases, a significally OLD date is reported by
the rtc (or even the "empty" data) So that case can be handled as
On shutdown, rockbox would store the battery state (as Bluechip
tought) as well as the date of shutdown.
On startup, rockbox would reuse the stored battery state for
charging(as Bluechip requested) but only if the shutdown was not more
than five days ago.
