Hello
I feel useful to tell this because someone here, has told the contrary and that made me to wrong results
If you, for example, type "journalctl --list-boot" then you obtain not the list of the date of the boots and shutdown, but the list of the dates of the login logout of the session you are logged in, as evidence and this morning I had some clear difference time, startup 07:59:40 login 08:38:26

Re: Journalctl needs sudo
You sure about that? The output with or without sudo is the same.
7:55.03 is the time I ran the command because boot 0 hasn't been shutdown yet.
06:06:35 is the time that systemd started, which will always be a few seconds after the initial kernel init, which is why journalctl timestamps for the initial kernel loading before systemd starts are always the same and disagree with dmesg output. But systemd starts way before user login.

Re: Journalctl needs sudo
Yes I am sure because I first enter a no sudo account and typed the command that gave the date 08:20 for example, and then I logged out this session and logged in a sudo account and typed the command without sudo and I got 08:38:26 and then with sudo I got 07:59:40

Well that's pretty clear...never seen that before, but never considered running administrative commands from a non administrative account either.Code: Select all
Hint: You are currently not seeing messages from other users and the system. Users in groups 'adm', 'systemd-journal' can see all messages. Pass -q to turn off this notice.
So you don't need sudo if your user is in group
adm. The primary account created during installation is always in this group in Mint.Code: Select all
