Clock is very inaccurate #14

It only takes a month for the clock to be many minutes off. Firmware needs update, or other fix?

My 860C goes forward 5 minutes/year. Acceptable tolerance. I have never delved into the management of the clock, I don't know if a calibration is foreseen. If you are able to compile, you can try changing the value of:

define SECONDS_IN_DAY 86399

in the rtc.c file.

FYI - My 860C goes forward as well, last updated at the end of March (when the clocks changed) and today it's 100 minutes forward.

Ok, sounds like a correct clock is something I can't expect. No big problem, but just found it a little strange, but maybe more complicated than I think.
