How can I know that my system will correctly change time next weekend. I am running HPUX 11i.
Thank you,
Steve

Re: Time Change
It will handle it just fine. Your system keeps track of the system time using UTC (or GMT), and the time zone is just how the date/time is represented to users.
To see how the time change will effect things like cron jobs, take a look at 'man cron', under the section "Spring and Autumn Time Transitions". It explains how it gets taken care of.

P.S. Our mainframe guys still have to re-IPL their system to handle the time change. Be glad you don't support one of those. :)

Re: Time Change
man of tztab has a better explanation of how timezone changes are handled.
Just ensure your TZ is set to a correct value.
# echo $TZ
# more /etc/TIMEZONE
As long as you have a correct timezone defined, you should be good to go.
Look at /usr/lib/tztab file too.

SolutionUse the attached Perl script, dst.pl. dst.pl -u will display full usage but dst.pl -n will display the next time change. It uses exactly the same underlying function (e.g. localtime) as would be used, for example, by the date command so if dst.pl works properly, you can be confident that all is well. As a bonus, this script works under Windows as well, if you have Perl installed.

Re: Time Change
Your server should adjust the time correctly as long as your Timezone is set properly, and you can check on Monday, just by using the date command and it should show you the correct time for your Time Zone if not then you can either change it on the command line or through Sam, your choice.
