change time on systems

[Musa I. S.]

How do i go about changing the time on some of my HPUX servers.

[Court Campbell]

use the date command.

And you could also use sam.

Hi:

To reset the time on your server, do:

# date [-u] [mmddhhmm]

The '-u' means specify the mmddhhmm in UTC time.

This will step your date/time forward or backward in *one* change. If you are moving backwards in time, stop time-sensitive processes like databases and the 'cron' daemon. Going forward is generally benign.

See the 'date' manpages.

Consider using the "date -a ..." option if you are going to set the time back. It skews the clock similar to "ntptime -B" and you don't have to worry about time sensitive applications.

Hi (again):

I agree with TTr with regard to setting the time backwards using 'date -a'. This is fine for relatively small decrements if you care to wait long enough for the slew.

You should always setup NTP (network Time Protocol) to eliminate problems like this in the first place. This can be done via SAM or via simple configuration setup:

Setup at least three reliable, external time sources:

Make sure you have the correct timezone. You may have the correct UTC time but the wrong zone.
Right now I get for UTC:
$ date -u
Tue Jun 17 20:04:53 UTC 2008
