Uptime Wrong

[rightsidedown]

Hello All
Has anybody ever seen uptime be wrong in AIX 5.1. I have a system that is showing an uptime of 12961 days. The system has been up for a while, but not even close to that long. Thanks for your help.

That looks like the number of days since the UNIX epoch. Was the system time wrong (as in Jan 1, 1970) when it was first booted?

I think the uptime messed up over the weekend. The system has been up for over 500 days...close to 600 I think.

Well, I just caculated it out, and it is an amazing coincidence that 12961 is the number of days since Jan 1, 1970. What does your "date" command come back with?

I am not sure what the issue could be. One glaring issue is that you have not patched your server in a really, really long time. What ML is this box currently at? "instfix -i | grep ML" I am just guessing that there may be a bug in the uptime command that is rarely seen since servers usually get rebooted more than once every year or two ;-)

The system is at 5.1 m/l 04. We do not get to take the system down to do any updates until it breaks. It has been running fine.

Sounds like a good opportunity to get it patched now that it is "broken". I will keep the rest of my comments about who should control patching schedules to myself.
