One of these is readily apparent from Steve's example, and was
described in Fred Bone's posting: there are several cases where the
same abbreviation is used for at least two different world time
zones. (As an example, I believe CST is another abbreviation shared
by two world time zones.)
Moreover, the abbreviations for time zone(s) in one's own country
might not be readily familar to those visiting a Web site from a
distant country, for example.
Finally, the names of these zones are subject to the usual vagaries
of human politics.
For all of these reasons, it is far preferable to simply provide
the offset from Universal Coordinated Time (UTC).
