#1 there should be a timezone setting that will lock you into the correct zone without the changes twice per year.

#2 The timezone data will be changed to reflect these changes for Linux and BSD distributions. I presume (not running an instance of SOLARIS for more than ten years) that there will be an update for Solaris to do that as well. If not, see #1.

In the EASTERN USA I have the timezones EST, EST5EDT, New_York. EST does not change, but if we adopt year round DT it would be EDT and that is missing from the zoneinfo so I might set to an adjacent zone that would not change, or wait for the update to the NewYork zoneinfo.

You mean IRDT has been cancelled, and IRST is to be used whole year? I think it should be export TZ=IRST-03:30

The
export TZ=IRST-03:30
is good to make tests in the current shell:
date
ls -la

To change the system default in Solaris 10, put
TZ=IRST-03:30
in
/etc/default/init
and reboot.
