I lost utility power for 2 hours today while at work (on my home
machine). UPS probably help for 20 minutes, or so. Just out of
curiousity, is there a way to determine previous system uptime. I know I
was getting close to 11 months, which would be a record for me.

Thanks,
festus

reboot system boot 2.6.28-gentoo-r5 Thu May 13 16:39 - 17:30 (00:51)

OK, so after looking at "man last", I tried

festus@localhost ~ $ last reboot
reboot system boot 2.6.28-gentoo-r5 Thu May 13 16:39 - 17:30 (00:51)

wtmp begins Sat May 1 08:23:36 2010

which doesn't really help much.

Any other ideas,
festus

Damn - log-rotate cleans wtmp monthly

Strange. My wtmps are quite older:

wonko@zone ~ $ last -F |tail -n 3
reboot system boot 2.4.18-xfs Sat Jul 13 00:08:20 2002 - Sun Jul
14 02:53:25 2002 (1+02:45)

wtmp begins Sat Jul 13 00:08:20 2002

> Any other ideas,

You could wait with your next reboot until May next year. Then it would no
longer matter much as you broke the record anyway.

The system logs boot and login dates in /var/log/wtmp, the last command
shows the content of this binary file.

last | grep "system boot" | head

Hope you broke the record,

This is mine:

root@smoker ~ # last | grep boot
reboot system boot 2.6.30-gentoo-r8 Sun May 9 20:51 - 20:56 (4+00:05)
reboot system boot 2.6.30-gentoo-r8 Sun May 9 03:49 - 19:21 (15:31)
reboot system boot 2.6.30-gentoo-r8 Mon May 3 17:29 - 14:48 (4+21:18)
root@smoker ~ #

Isn't the last part of the line the uptime? I haven't done the math to
say that it is, just curious. Also, I have logrotate set to rotate
mine. I delete them after a while or when I need disk space. They do
consume space after a while.

The default logrotate.conf rotates wtmp monthly.

Too late now, but installing app-misc/uptimed will answer this
