# uptime
eg output
6:38pm up 9 days, 3:36, 3 users, load average: 0.27, 0.27, 0.27

or check from shutdownlog, eg:
# cat /etc/shutdownlog
--> last entry

14:55 Mon Nov 17, 2003. Reboot: (by !root)--> the last time system was rebooted

or check rc.log
# cat /etc/rc.log

No-one mentioned the world's shortest unix command (or one of them) - "w".

Neither did they mention the 'uptime' of this thread!
