TimeZone
From ThorxWiki
Because people keep thinking that the "EST" in my `date` command must be incorrect...
Please run the following command (should be fine in linux, under solaris change the path to search under to /usr/share/lib/zoneinfo)
find /usr/share/zoneinfo -type f | xargs /usr/sbin/zdump | grep EST
Now try it without the grep, and note the time zone identifiers, ...these are incorrectly assumed by most people to be unique. I believe (without references) that the timezone acronyms are based on local names - there is no global cooperation in keeping the namespace clean.
