This thread is 3 months old.
I have noticed that the output from "uptime" has a variable format according to how long the machine has been up and whether any of the fields are a whole number (e.g. If you have been up an exact whole number of hours you don't see the minutes figure).
There is no maximum that I know of but I've not seen machines up for more than about 5 years.
Please give an example of your "uptime" and mention what Operating System you have. The "kstat" command is a Solaris command.

NAME
ruptime - show host status of local machines
SYNOPSIS
ruptime [-ar] [-l | -t | -u]
DESCRIPTION
The ruptime utility gives a status line like uptime (see uptime(1)) for each machine on the local network; these are formed from packets
broadcast by each host on the network approximately every three minutes.
Machines for which no status report has been received for 11 minutes are shown as being down.
Normally, the listing is sorted by host name, but this order can be changed by specifying one of the options listed below.
OPTIONS
The following options are supported:
-a Counts even those users who have been idle for an hour or more.
-r Reverses the sorting order.
-l | -t | -u These options are mutually exclusive. The use of one overrides the previous one(s).
-l Sorts the display by load average.
-t Sorts the display by up time.
-u Sorts the display by number of users.
