This is exactly why I said in my original post that I sometimes want this - in many cases I don't, but whenever a user has explicitly input the data I'd like to easily be able to return it in the same timezone. I can (and do) store two columns in the database, but I'd prefer the database and JDBC interface natively support this as a single data type. Right now, supposing you have two columns, EventTime TIMESTAMPTZ and EventTimeZone TEXT, you'd have to do something like the following in your query to get the data returned to the application properly: SELECT (EventTime AT TIME ZONE EventTimeZone) || ' ' || EventTimeZone
