You said that your PostgreSQL time zone was set to UTC-6. Are you
sure that's the case? What's the output from 'SHOW timezone'? Also,
what's the system time zone set to?
The reason I ask is because, for me, setting the time zone to UTC-6
gives me a time that is six hours AHEAD of UTC, which wouldn't be
appropriate for South America:
rhaas=# select now() at time zone 'utc', now() at time zone 'utc -6';
timezone | timezone

2011-09-21 16:31:26.082048 | 2011-09-21 22:31:26.082048
(1 row)
The rules for interpreting time zone specifications are arcane enough
to make me suspect that this isn't a bug even though it seems rather
odd, but in any case it would be useful to know how many hours
PostgreSQL's timestamp is behind (or ahead of) UTC and similarly for
the operating system.
