As long as I can convert from unix timestamp to a friendly date/time, I dont mind if its off from the wall clock time by a few seconds. Parsing uptime or last reboot was a bit more of a pain to covert into something you can return a value of just days to.īash example: sysctl kern.boottime | awk '' | tr -d ,) Id rather leave leap seconds out of the equation. I also use sysctl to track this, or at least I found it the easiest to parse. ![]()
