Hi Andrew, Finally got around to trying to implement your solution.
It works fine with fixed offset timezones, but when I try it with EST5EDT I get the following: protocal2=> select start_datetime,cast(cast(cast(start_datetime as timestamp(0) without time zone) as varchar)||' '||B.timezone_ch as timestamp(0) with time zone) from reservation A, location B where appt_key = 7 and locn_key = 102 ; ERROR: invalid input syntax for type timestamp with time zone: "2006-07-13 09:20:00 EST5EDT" when I change timezone_ch to EST it works like a charm: protocal2=> select start_datetime,cast(cast(cast(start_datetime as timestamp(0) without time zone) as varchar)||' '||B.timezone_ch as timestamp(0) with time zone) from reservation A, location B where appt_key = 7 and locn_key = 102 ; start_datetime | timestamptz ------------------------+------------------------ 2006-07-13 09:20:00-04 | 2006-07-13 10:20:00-04 (1 row) Any thoughts?

I hope/assume your solution > works with "EDT" instead of "-3", I will test it soon. Should do, although you'll need more than EDT. EDT is also fixed: it's UTC-4. EST5EDT isn't, though, so you could use that (you'd need to improve your schema, though, because you had char(3) there, and not all time zones are 3 characters long). But to answer your question, yes, it works. I just tried it. A -- Andrew Sullivan | [EMAIL PROTECTED] Information security isn't a technological problem.
