I would recommend against storing the abbreviation. The abbreviations
are not globally unique and don't follow daylight savings. If you want
to store the original time zone, I would use the full name.
Something like this might be relative to your interests:
INSERT INTO tbl (ts, tz)
VALUES ('2016-01-20 00:00', current_setting('TimeZone'));
This will do the right thing regardless of where the client is (unless
it's set to "localtime" and then it's useless).
