We have uptime but is there a starttime?

Hi gurus,

Is it possible to get the time on when the server was re-started or does the output from who -b is the answer to my question? UNIX flavour is Solaris.

The uptime command gives information on how long the server has been up but I want to know when the server was started. The output from who -b does not seem right.

Any feedback will be very much appreciated. Thanks in advance.

Code:

server01 33% who -b
   .       system boot  Jul 11 09:22
server01 34% uptime
  2:35pm  up 2 day(s),  5:13,  8 users,  load average: 7.47, 7.35, 8.20

But it is correct:

Code:

$ who -b
   .       system boot  Jun  8 13:11
$ date
Tue Jul 13 07:18:30 METDST 2010
$ uptime
  7:18am  up 34 days, 18:07,  71 users,  load average: 0.79, 0.86, 0.98

2010-06-08 13:11 + 34 days = 2010-07-12 13:11
2010-07-12 13:11 + 18:07 = 2010-07-13 07:18

Even though you have your answer, the last reboot/boot time can be found with the 'last' command

Quote:

bash-3.00# last boot

wtmp begins Tue Jul 13 02:30

Hi Pludi,

Thanks a lot ... How did you do the calculation ... ??? I think that is the "trick" that am looking for or did you calculated it manually ... ???

That way calculated manually to illustrate the relation between boot time as give by "who -b"/"last boot", uptime, and the current time.
