Really? No one knows where this is stored?

Ok, I have some info. Still not sure what to do with it.

Timezone data is stored in data files in the directory "/usr/share/zoneinfo"

However, the timezones appear to be further configured by the file "tzmappings" located in the directory "/opt/app/jazz/server/jre/lib"

It is possible deleting some data files from "/usr/share/zoneinfo" would drop the timezones from the list, but I do not have root permissions on the server. Anything above /opt/app/jazz I cannot remove or overwrite.

I tried editing the "tzmappings" file, but that appeared to have no affect. It also has the following warning in the file:

# @(#)tzmappings 1.5 01/03/18
# This table describes mappings between Solaris time zone IDs and Java time zone
# IDs. Fields are separated by a single TAB ('\t'). Lines must be in the ascending
# order in ASCII. (non-ASCII characters can't be used.)
# NOTE
# This table format is not a public interface of any Java
# platforms. No applications should depend on this file in any form.
# This file has been generated using programs. Do not edit this file manually.

What programs are used to edit the tzmappings file? This appears to be a secret as I could find no reference by Googling it.
