How critical is time to the vCenter Appliance?

I have a vCenter 6.7 appliance. We had a planned outage to shut down the system and when it was brought back up vCenter was not starting correctly. I noticed that our timeserver was not receiving a valid time signal and was not providing anything even close to an accurate time. If I fix the timeserver and restart vCenter "should" things return to normal or will I need to delete and redeploy vCenter? Thanks.

Time is pretty critical. Remember that VCSAs rely on PSCs, whether embedded or external. PSCs handle authentication requests, store licensing, etc. Similar importance levels to a domain controller, in my opinion. You shouldn't have to delete and re-deploy a VCSA to correct the issue, but when you correct the time concern you'll noticed a "jump" in timestamps in logs, etc.

Just fix the time and reboot the VCSA

OK, thanks everyone. This is what I was thinking but I wanted to verify. I'm planning to go back and fix this next week. I'll post what happened.
