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.


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.
