Hi Guys,
Is there a tool that will show me the total uptime (availability) of a
machine between reboots?
That is, if the machine was up for 24 hours and then shutdown for an hour
and then up for 23 hours I want an answer of 47.
I need this for charge-back of departments using cloud computer which

Your solution will work, of course, only on a tidy shutdown. For unplanned
shutdown (aka - power failure) it will not work.

This morning I took part in a meeting here at work where something related

Hi all,
Hamakor, the Israeli Non-profit organisation for Free Software and Open Source
Code will hold a general assembly on Thursday, 17 February, 2011 in the
Shenkar College in Ramat Gan. The assembly will be held at 18:30 in room 304
(in the old building of Shenkar).
On the agenda:

Thanks for all your tips!
I found that the information is basically available in 'last -x'.
Below is a rough script I put together to estimate total times rounded to
hours:
Thanks,
