MacBook Air M1 2020 changing time back ~13 month after wakeup from sleep.

My MacBook Air M1 2020 changes time back ~13 month after wakeup from sleep. This looks like a duplicate of MacBook Air time changing back ~5 months … - Apple Community but sadly this post is to old to ask the OP if they found a solution.


Settings to reproduce this:


  • Set time and date automatically is switched on.
  • Set timezone automatically using your current location is switched on.


What I already did:


  • Turned off set time and date automatically which seemed to fix the issue but is no long term solution.
  • Changed the timeserver from time.apple.com to one of ntp pool which did not fix the issue.

Hi a brody,


Thank you for your advice. I tested it connected to the power adapter and it still happens. Whats interesting is, timed seems to get the right time via ntp and then fails for some reason and sets the time to October last year.

If I set the time manually and do the same (connected to the power adapter or not) everything works fine (no wrong time after sleep).

Interesting addition: After switching set date and time automatically and setting the correct date and time manually turning on set date and time automatically sets date and time to the wrong date and time again. The "funny" thing is that setting date and time to the correctly received date and time via NTP fails afterwards.
