Clock is 40 seconds fast or 20 seconds slow...

#1
No matter what I do I can't get the time to be the exact correct time on my 2003 Toyota Corolla. So for instance when the time is 8:00 and 0 seconds, I set it to 8:00 then 20 seconds later the time goes to 8:01 making the time 40 seconds fast. I also try to set it to 7:59 so that way 20 seconds later it will turn to 8:00 making it 20 seconds slow. No matter what I do... the minute changes at 20 seconds after the minute changes on my phone.

I had an issue once with a clock in one of these cars where it stopped working, but was fixed after a few tricks. One of the tricks was to unplug it from the dash and let it sit, have you tried this? Maybe it needs to reset as to have no saved info
