Wrong clock time when ignition is off

Hi. I have problem with wrong clock time, when I turn ignition off, clock time changes to completely different (its not time zone difference) - look like 2 separate clocks.
Problem started to appear when I updated sync from 21265 to 23188.
I read other threads and think it could be something about master clock, I compared APIM as-built from forscan with factory and its the same. Any ideas what can I do?
My car - Focus 2017.

Do you have a error message, if so what is it?

Did you do a sync master reset after the upload to the car?

I did.

Please post your current AB for the APIM your currently using.

Well AB looks correct to me. BCM is the Clock Master in a Type C in that year and model.

I somehow remember this being an issue with latest builds on some units, but I do not remember a solution for it other than downgrading to earlier builds…

I think it had something to do with DST…

Same with my smax… started after a few last updates I think almost a year now. I just ignore it… its only when ignition is off.

Particularly NON-NAV units…there was no solution other than downgrade.
