You are correct.

However, how about this:

                            version
---------------------------------------------------------------
 PostgreSQL 7.1.3 on i686-pc-linux-gnu, compiled by GCC 2.95.3
(1 row)

=> select now() as "MESZ", now() at time zone 'MEZ' as "MEZ", now() at time zone 'UTC' as "UTC" ;

          MESZ          |          MEZ           |          UTC
------------------------+------------------------+------------------------
 2005-04-25 17:13:19+02 | 2005-04-25 16:13:19+01 | 2005-04-25 15:13:19+00
(1 row)

Is that eventually it ?
