I just woke up to all my lights on and my server off. It was a power cut, but... Checking the logs for Proxmox, it seems to have lost memory.. There were no logs for 10 days and when rebooting it said the system clock was off by as much (931,920 seconds = 10.7 days). What do? Anyone seen this before?

Thanks all, gonna replace the CMOS battery as suggested. Got a few in storage. 🖤
