Hmm. I don't know how many kernel printk-s you have and how often do you write to kmsg. I was thinking about something like this:
echo 0 > /...printk.../time dump buffer to /dev/kmsg echo 1 > /...printk../time
- If you would have several kernel printk-s in the meantime, then those would not have timestamps, but you kinda can roughly guess it
write [1243] foo > /dev/kmsg write [1244] foo > /dev/kmsg << printk(bar) <timestamp ~[1244,1245]> write [1245] foo > /dev/kmsg
Maybe this won't suffice.
