Re: BUG #5031: DATE_TRUNC returns the wrong value when specifying MONTH

You're correct. When I run this from psql it returns the correct result. When I run it from DBVisualizer, which I normally use, it adjust the result to my local time zone. Thanks for looking into it. Sorry about bugging you with that.

Thanks,

Mark

Okay ...

postgres=# set timezone = GMT;
SET
postgres=# SELECT DATE_TRUNC('MONTH', CURRENT_DATE);
date_trunc
------------------------
2009-09-01 00:00:00+00
(1 row)

I suspect there's something you're not telling us, like you're
using a client-side library that is doing timezone adjustments
behind your back.
