Manjaro/KDE randomly wrong time(many years ahead) after laptop sleep

[llj098]

Hello there,

I’m using manjaro linux on a lenovo laptop. In KDE time setting, the set date and time automatically option enabled.

When I open the laptop lid, the laptop wake from sleep state. And the system time randomly goes wrong.

Today is 2024.02.05, but the system time show the time is in 2078-03-11. After I reboot the system, the time is back to right.

Below are some logs:

Kernel version:

and also I use the ntpd -qg the time also goes to be right

I don’t know why this happens and how can I solve this?

Welcome to the forum. I’m just fishing for clues here, but what are the outputs of

systemctl status systemd-timesyncd.service

and

timedatectl timesync-status

[Mirdarthos]

Hi @llj098, and welcome!

In addition to what @Takakage said, perhaps this will help:

[root tip] [How To] Get your time/timezone right using Manjaro/Windows dual-boot

Difficulty: ★☆☆☆☆ The woes of dual-booting Manjaro/Windows Windows defaults to setting the (RTC) real-time-clock to local-time and Linux sets RTC in UTC (universal-time). This makes your time/timezone floating in space where it may be in doubt what time it actually is. Manjaro configuration The best approach to keep both working is to set your RTC (hardware clock) to UTC # timedatectl set-local-rtc 0 or use # hwclock --systohc --utc And enable a network-time-daemon on Linux. # systemct…

Also, make sure your setting in BIOS/UEFI is correct.

CMOS Battery? On reboot syncs through internet. In deep sleep relies on the battery for RTC.

[cscs]

I like configuring a script to sync time according to network on every net connection.
(which, depending on configuration, would also fire after sleep/suspend)

Thanks for the reply, right now the time is correct( goes wrong randomly)

Thanks for reply! I have already checked the link you post. But I have linux system on this laptop only.

And My time goes to Mar 2073, so It should not be the timezone issue?

Thanks
LJ

[llj098]

Thanks for the reply! I’m using a new laptop, it seems not a battery issue.

How can I determine if it is a battery issue?

Thanks!

[llj098]

Thanks for the link!

As my time goes to 2073, so it shoud not be a timezone issue?

[llj098]

update, If the system wake up, and there is no internet connection, where time will be wrong,

It happens everyday now, anyone can help?

Thanks!

[Mirdarthos]

@llj098

It happens everyday now, anyone can help?

Sorry dude,

Sounds like your BIOS/UEFI is out of whack…

[llj098]

Thanks for the reply, I just check the BIOS, the time is correct. What should I do to make sure the BIOS/UEFI issue? BTW, it is a new laptop, I just buy it two weeks ago.

This issue only happens when the laptop wake up after long(1 hour or longer sleep).

[Mirdarthos]

Only other thing I can suggest is checking the status of the systemd-timesyncd.service service:

systemctl status systemd-timesyncd.service

Additionally, what @cscs said, looks like a valid option to me:

@cscs

I like configuring a script to sync time according to network on every net connection.
(which, depending on configuration, would also fire after sleep/suspend)

So check the link he gave:

https://wiki.archlinux.org/title/System_time#Update_timezone_every_time_NetworkManager_connects_to_a_network

[llj098]

I just found an old thread(2013), Clock shifted to the future after suspend/resume / Kernel & Hardware / Arch Linux Forums It seems that I have the exact same issue.

[llj098]

My log shows

           Local time: 五 2078-03-11 10:46:42 CST
       Universal time: 五 2078-03-11 02:46:42 UTC
             RTC time: 一 2024-02-05 01:32:45

For my understanding, RTC time is hardware clock, the hardwire clock shows the right time, why do you say it is the bios’s problem?

Thanks

[Mirdarthos]

It does, and I don’t think there’s a fix for it. Or st least, I couldn’t find one.

So I suggest one of two thing:

1. Go with the advice @cscs gave you as a workaround; or
2. Reinstall Manjaro and see if the problem persists, and if it does, then you’ll have to apply #1.

Edit:

@llj098

why do you say it is the bios’s problem?

That was my understanding. But your link says differently:

Yes, it seems to be a kernel bug.

That was my understanding because this is the first time I’ve heard of it in 15+ years!

[scotty65]

What does the Manjaro Settings Manager (manjaro-settings-manager) show when you open it and select the “Time and Date” section? This is what my system, which always has the correct time (even after sleeping), shows:

[nikgnomic]

@llj098

the hardwire clock shows the right time

To set system time from hardware clock

sudo hwclock --hctosys

[llj098]

Thank you all guys. I think this is not a hardware problem.

I use two script to solve this. First script: /lib/systemd/system-sleep/time-shift

#!/bin/sh
case $1/$2 in
  pre/*)
    date +%s >> /tmp/suspend.log
    ;;
  post/*)
    date +%s >> /tmp/wakeup.log
    hwclock --hctosys
    date +%s >> /tmp/wakeup_shifted.log
    ;;
esac

second script:

➜  ~ cat /etc/NetworkManager/dispatcher.d/09-synctime 

#!/bin/sh
case "$2" in
    up)
        date +%s > /tmp/before_ntp.log
        ntpd -qg
        date +%s > /tmp/after_ntp.log
    ;;
esac
