[Solved] problem with system clock, just after 21.3 upgrade.

[revrob]

I am actively investigating motherboard/CPU/PSU replacement.

Meanwhile, I have shorted the CMOS settings using the jumper which set the hardware clock back to 2011 as expected, and I have reset everything to the BIOS settings suggested.
I have also checked hardware connections inside the system box, and all cables, to make sure they are firmly in place.

Reboot went fine, and I have seen a variety of behaviours since on waking from suspend, including panel clock self correcting within minutes, not self correcting at all, and suspend causing various clock future times/dates, and sometimes NOT causing them.

I have a detailed log. I have prevented any further automatic backups, but I can't prevent the automatic timeshift snapshots - I'm deleting any that have the incorrect timestamp.

I shan't post again unless something dramatic happens, or I have completed the hardware upgrade.

Thanks for the help.

I am not sure if this is the right place to post this but I accidentally discovered a bug in the Linux Mint Mate upgrade to 21.3 installer related to this.

One of my machines I updated a few weeks ago could not connect to the internet. Something about system clock not correct. I checked a sure enough instead of a March 2024 date it showed Nov 21 2023. I corrected the date and then access to the internet was restored.

Further investigation showed that the update removed the ntp service but did not install the timesyncd service. I have now confirmed this on two other upgrades. Once I installed the timesyncd service the clock stays up to date. So far the first one was a laptop and the other 2 are newer desktops. I suspect I will find this to be true for the rest of the desktops I am responsible for. The two newer machines were only off by 20 to 30 seconds so I would have not noticed the problem on them for a while.
The laptop was actually a 2013 Chromebook converted to Linux Mint a while back when they stopped updating it. I suspect the user ran the battery down and the machine powered off. After recharging the clock was really off.

Thx for this. It sounds a bit different to my "68hr fast clock after suspend" problem, which doesn't always occur now.. I'm too much of a newbie to know whether timesyncd service is working, but I can confirm that MOST of the time (not all) the panel clock corrects itself on wake up once connected to Internet. The PC is a desktop and I noticed the problem after updating to 21.3 using update manager. My dell inspiron laptop is unaffected.

This is a user forum where users help others users. It is not a place to report bugs.

If you feel the issue you have experienced is related to the mintupgrade process, then post your issue on linuxmint / mintupgrade: Issues and provide as much detail as you can.

This topic is specific to revrob's issue which is not the one you have described.

Since upgrading my motherboard, CPU, Memory and Power Supply Unit, this problem appears to have gone away.

This is exactly what happens to me.

After install systemd-timesyncd problem was solved.

Thanks.
