Because people keep thinking that the "EST" in my `date` command must be incorrect...
Please run the following command (debian styled linux has zdump in /usr/bin/, whilst redhat styled has it in /usr/sbin, whilst under solaris you'll need to change the find search path to /usr/share/lib/zoneinfo (and track down zdump, which I think will be in /usr/sbin, but don't quote me) :)
find /usr/share/zoneinfo -type f | xargs /usr/bin/zdump | grep EST
Now try it without the grep, and note all 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.
