My computer recently developed an error where the hardware clock displays the time as follows
System date [Mon 31/63/25755]
System time [63:28:25]
The clock runs.
I’ve tried all the usual tactics: remove CMOS battery, short the pins to force a reset, put fresh battery, reflash BIOS. Nothing.
On boot, I get an error on reading the hardware clock and the system defaults to 3 of September, 2025.
I think I’m looking at a mobo heading to the e-waste bin.
The board in question is a GygaByte AB350M-DASH. It still runs but it’s a bit annoying having to set the system clock every single time I boot up the machine.
Any advice on the matter is welcome.


Does the machine have internet access? If yes you should be able to have it set time from the internet automatically.
I second this. If you can deal with those microconnections to an NTP server, search for how to enable NTP. On a systemd Linux system it should be a
timedatectloption, I think.Done and in the process it even fixed the hardware clock.
Very interesring!
