Thanks for that, Martin. I knew the capability had to be /somewhere/
but I couldn't find it!
However, in this case the RTC was not being driven correctly, and it was
losing its setting under some circumstances - I think the
battery/super-capacitor was being disconnected over power-down! I was
pointed to the notes about correcting the register settings so that this
wasn't done, and backup power was kept. I wrote this up in a small note:
