Henrik,
I have no access to Tru64 4.x systems...
Here are some output examples from "uptime", I have implemented a simple
client script which reports the uptime to the hobbit server, every day I
had a blackout for 1 hour in de RRD. I have fixed it, the reason for
that was:
# date
Sun Aug 7 17:19:22 CEST 2005
# uptime
17:19 up 90 days, 56 mins, 1 user, load average: 0.00, 0.01, 0.00
# date
Sun Aug 7 17:23:58 CEST 2005
# uptime
17:24 up 90 days, 1 hr, 1 user, load average: 0.00, 0.00, 0.00
# date
Sun Aug 7 17:24:21 CEST 2005
# uptime
17:24 up 90 days, 1:01, 1 user, load average: 0.02, 0.02, 0.01
==> There are 13 parameters, if uptime is some days + 1..59 mins (or 1 hr).
==> For the next 23 hours we have just 12 parameters.
Here the output on Solaris 8:
$ uptime
5:30pm up 8 day(s), 16:42, 1 user, load average: 0.06, 0.02, 0.02
On Linux:
$ uptime
7:30pm up 8 days, 17:20, 1 user, load average: 0.00, 0.00, 0.00

And here some outputs from "vmstat -P" from Compaq Tru64 UNIX V5.1B
(Rev. 2650)
