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
