The patches state that these should be installed in single user mode and a reboot must be done immediately after install. This is on all patches. I'm having trouble getting down time to do the single user mode and reboot on most of the servers I support. Is this really needed for the 2 DST patches for Solaris 8 and 9?
One of the patches is for libc. I wouldn't want to have that in place without a reboot for long. I'd postpone installing that until I could get a reboot scheduled.
The patch for zoneinfo shouldn't cause a problem without a reboot, but any processes still running will not pick up the changes. The reboot ensures that all processes have restarted.

It's not so much what you set the system to as what you need time routines for.
If *no* process on your machine will ever need to convert using a US timezone, then it's likely irrelevant.
The timezone setting is per-process, not per-system. There's a system default, but any process can change or override it. This is especially noticeable on machines that are used by people in multiple timezones simultaneously.

If you set the TZ to GMT you won't have to worry about DST. But your system will not display local time in some cases either.
Don't forget that cron jobs are executed on local time!
Local time is always computed on the fly in Unix, the system time is always the number of seconds since the epoch, GMT (UTC). So not installing the patches will only cause problems for hosts in timezones that have made changes to their Daylight Savings Time schemes since the last set of patches came out, as in the US.
