The input is done using an internal lookup, not your system's time zone
database. Much faster; setting time zone variables for every input will
be substantially slower (though I haven't measured how much, it will
involve opening files etc etc).

The feature is implemented as a function call to timezone(), which
returns a string. If it stayed a timestamp or something like that the
time zone can not be "frozen" through the formatting/output process.
