I put my laptop into sleep by just closing the lid and sometimes after wake up the clock shows wrong time and date which results into web sites not loading until I change it back and then I also lose logins to my previously logged in websites and have to re-enter the logins.
I don’t have dual boot so it’s not Windows messing with the Linux time issue I was able to find.
I use automatic time and date with my time zone selected. Not sure what I should do about this.
I’ve tried to enable RTC in local time zone but that made things even worse so I disabled it again.
I just got home. You’re right that it’s using NTP. I went into BIOS and checked system time and it was 1h behind so I corrected it. timedatectl shows that system clock sync is OFF so I used hwclock --systohc command to sync with system clock and will see if that causes any issues. If it wont work then I’ll try to just stick with your way of doing it. But thanks for letting me know about the hwclock command.
