I had a Unix machine on ups battery backup. Ran 8 years. It was a communications hub, and after I sold the company no one shut it off. My wife (I sold her with the company), shut off the cron processes, but though it was doing something else. It was but nothing of consequence. She called me one day and asked if she needed the NCR system running in the back closet. That's when I asked her to type in uptime and hit enter. Weird. System was the size of a large book.

What I meant to say above is you do this..even in linux.

#uptime
8 years 2 months 3 days 4 hours 10 seconds.

It reports that.
