Experiencing errors with my Mac OS clock after Sequoia 15.0.1

I am running Sequoia 15.0.1 and have been experiencing errors with my Mac OS clock for months. Strangely the clock seems to be running slow, losing about 30 mins every 6 hours, like an analog clock. I have tried turning on and off Auto Time and Date setting, same with the Auto Time Zone setting. The system clock ends up being wrong with these toggles turned on or off. Manually setting location and time leads to the wrong time and date.

I have tried running Terminal commands that have been suggested by various people e.g. sudo rm /var/db/timed/com.apple.timed.plist

Not sure what else I can do!

BTW, the Terminal NTP command did not solve my problem. For the following several days, my clock was out of sync. My computer upgraded to 15.2 though and that for me solved the issue, my clock is now properly in sync for several days.

It seems that for some people, 15.2 broke clock sync, but for me it fixed it...

That's fair enough! :)

So far, my clock is now keeping time OK for the past 18 minutes. A good test will be in a few hours.
