What isn't documented is why the sign changes for +0300 but not +03:
test=> set timezone='+03:00';
SET
test=> select now();
now
-------------------------------
2011-04-26 18:22:55.571638-03
(1 row)
test=> set timezone='+03';
SET
test=> select now();
now
-------------------------------
2011-04-27 00:23:00.627179+03
(1 row)
It is the colon somehow:
test=> set timezone='+03:';
ERROR: invalid value for parameter "TimeZone": "+03:"
test=> select now();
now
-------------------------------
2011-04-26 18:24:36.921323-03
(1 row)
test=> set timezone='+03:0';
SET
test=> select now();
now
------------------------------
