This, and by any chance do you have a firewall setup (either software or hardware)? Check to make sure that NTP (Network Time Protocol) is enabled. If you have "Set time automatically" turned back on, it should reach out and grab accurate time.
As for the CMOS battery, try this. Set the time of your computer in Windows, if you know how to do it in the BIOS/UEFI do that as well. Then do a proper shutdown.
Unplug the computer for a couple minutes, and see if it remembers the time after you plug it back in.
Might be worthwhile checking if there's a BIOS/Firmware update for the motherboard a swell just in case.
