It’s kind of frustrating with dmesg timestamps. It basically show [seconds.nanoseconds] since last boot … that’s really accurate, and totally useless for humans that can’t do that math in their heads .
This guy at wrote a great python script as a solution.
With reference to one of the comments at that blog, an even more elegant solution would be to simply use /var/log/kern.log , it’s already there 🙂
