However, if you had checked the DateTime documentation and you'd find
"time_zone_short_name" under "Get Methods" at
http://search.cpan.org/~drolsky/DateTime-0.42/lib/DateTime.pm#%22Get%22_Methods
Note, again however, the caveats on the DT:TZ method
(http://search.cpan.org/~drolsky/DateTime-TimeZone-0.73/lib/DateTime/TimeZone.pm#$tz-%3Eshort_name_for_datetime(_$dt_))

Moreover, these names are not unique. For example, there is an "EST" at
both -0500 and +1000/+1100.
