Every 30 mins or sometimes much longer the system time changes with the event --- The time service has set the time with offset 15481355650727981 seconds.

The time always reverts back 37 hours to the current time, visually it goes back 1 hour, PM switches to AM and Monday becomes Sunday.

Adding a task to sync the time every 5 minutes helps but doesn't solve the problem...

I have read this answer, but I do not think I have the same root cause. Windows 7 time keeps changing by itself

I have attached a screen shot of the event
