Clock is 30min late every morning

Question

Clock is 30min late every morning

Hi. Since the last three days, every time I wake up my macbook for the first time that day the clock is exactly 30 minutes late.

The time goes back to normal after some time or when I go to Date & Time Preferences, untick and tick again the checkbox for "Set date and time automatically (Apple Europe)".

Details:

MacBook Pro retina late 2013

Sierra 10.12.6

CEST time zone

Any ideas?

Thanks

MacBook Pro with Retina display, macOS Sierra (10.12.6)

Greetings Przemek Tomulik,

Thanks for using the Apple Support Communities.

I see that since the last three days, every time you wake up your MacBook for the first time the clock is exactly 30 minutes late. This is corrected by going into the Date & Time preferences or after some time. It's important to make sure that the clock always displays the correct time, so I'm happy to provide some support.

I suggest some software isolation troubleshooting for this issue by testing in another user account and safe mode to see if you get the same result. Please use the steps in these resources:

Let me know the results or if you have any questions.

Have an amazing day!

Hi Becky, thanks for the answer. Unfortunately, I was able to reproduce this issue on another user account and in safe mode. The case is always the same - after some time in Sleep mode the clock is late (from a few minutes up to 30 min).
