Okay, now just wait and see what happens. When will you know if it'll do it again? How often did it happen?

You reset the time sync service, told it to find a time master and told it to not wait to update.

Per the other random thread this system isn't bound to a domain.

Is the system constantly resetting to the same date and time?

Yes,

Then it goes to 3/3/2019, randomly as well.

So the system isn't just resetting to a time in the past but randomly jumping around?

yes, according to the events.

thinking it might be someone on site doing it, but times dont add up.

I doubt someone onsite is changing the time to be incorrect.

I've had to change the time to the past or distant future to get software that the business owned to work. From the devs they said "just change the date to X and it'll work for so many days etc".

This because their licencing dept was slow to provide licensing.

I've seen/heard of that but they werent putting anything on this computer

Basically you registered the time service, then started it, then re-synchronized the clock with it's source.

Check and make sure there are no scheduled tasks running that fiddle with he time as well.

Ya this is a good idea... if you didn't set it up and manage it's life, someone else coudl have some weird tasks going for whatever reason.

I see something for Time Sync in task scheduler

I noticed that it set it's time an hour ahead

the time sync as in "Internet Time" sync?
I've had issues with that in the past.
Like it's off by an hour and causes issues

Those could be the defaults. You'll have to see who created them and what they do.

I've seen the time slip, usually caused from a aging bios battery. But where time is jumping all over the place. That's a new one.

Slip meaning time goes more slowly. So you change it at 4PM Monday and by 8AM Tuesday the clock is some random amount of time behind.

This is a time jump, not a slip.

An entire hour ahead, would be a timezone issue. If it reoccurs.
