Solaris

Hello,
I've been looking at coming up with a time change on my Sun workstations since daylight savings time comes early this year. Someone at work told me that a sun patch is available if you have a maintenance contract. It was recommended to just set your systems to GMT time zone. How is this done using the date command or should it be done different?

Thanks,

The patches are in the Recommended patch cluster which is available to anyone. You should be able to download it and install.

If I don't want to use the patch, what is the correct command to reset the time and zone to GMT?

Thanks

Sorry, your comment indicated you thought you couldn't get the patch. Simply edit your /etc/TIMEZONE file and replace the current TZ setting with one of the filenames in /usr/share/lib/zoneinfo. So if you wanted to do just GMT, you'd have:

Code:

# @(#)init.dfl 1.2 92/11/26
#
# This file is /etc/default/init.  /etc/TIMEZONE is a symlink to this file.
# This file looks like a shell script, but it is not.  To maintain
# compatibility with old versions of /etc/TIMEZONE, some shell constructs
# (i.e., export commands) are allowed in this file, but are ignored.
#
# Lines of this file should be of the form VAR=value, where VAR is one of
# TZ, LANG, or any of the LC_* environment variables.
#
TZ=GMT

If you can't reboot, you'll need to change your TZ environment variable.

That's if you want to change the entire system. Otherwise you can just set your environment variable and the time will be displayed for just you as GMT.

Found the fix, made the adjustments for testing and it works.

Thanks

Just an FYI....you should check to see if any of your apps that use java need the java DST update as well. it depends on the version as well, but DST doesn't end just at the OS.

if the application uses these classes, you should update your java as well. you can usually find out from your vender for your app. In some cases, you need to reinstall java, in some cases it is as easy as using the tzupdater.
