Getting date with timezone offset

Question

I am trying to extract the date from a query in postgres. The timestamp is stored as UTC, so if I have 1/1/2014 02:00:00, I want the date in pacific time, to be 12/31/2013,

Answer 1

I figured it out, using the interval, I can subtract the offset and then get the date.

SELECT '1-1-2014 02:00:00'::timestamp + INTERVAL '1 hour' * extract(timezone_hour FROM '1-1-2014 00:02:00'::timestamp at time zone 'America/Los_Angeles');

Adding the answer here, since I am sure this question might be something others would want to know.
