Hi!
I propose to we configure our kernel to emit timestamps in kernel messages.

the "dmesg" command.

processes (like systemd) inject messages there.

I'm not sure I like to enable it by default as it also makes it a pain
to compare 2 dmesgs as you cant do a simple diff anymore.
Whats more, it can be enabled dynamically when really needed by adding
"printk.time=1" to the kernel command line.
I used to have it enabled in kernel-tmb during
(sigh, pressed send by mistake)
I used to have it enabled in kernel-tmb during some debugging, but
disabled it again when I remembered it can be enabled dynamically.
