Description:=20=20=20=20=20=20=20=20
Below is given psql output - I am in timezone UTC+05:30 (India) as shown by
select now() output below.
When I give "SELECT extract(epoch from now() );" the output is
1325872658.xxx=20
I would expect a slightly incremented value when after a few seconds I give
the command "SELECT extract(epoch from now() at time zone 'utc+05:30');" .
Nut I get the value 1325833067.xxx which is the value for utc-05:30 !!!
And when I give "SELECT extract(epoch from now() at time zone
'utc-05:30');", I get 1325872672.xxx which is what is expected if I
specified timezone +05:30 !!!
