Yes, it does. It doesn't (currently) record the time zone name, but
rather only the offset from UTC. If a time zone name (rather than UTC
offset) is given, it is converted to the UTC offset *at that
timestamptz* when it is stored. For time zones that take into account
DST, their UTC offset changes during the year, and PostgreSQL records
the equivalent UTC offset for the appropriate timestamptz values.
There has been discussion in the past on storing the time zone name
with the timestamptz as well, though no one has implemented this yet.
