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.
