Re: Re: timestamps cannot be created without time zones - Mailing list pgsql-bugs

Hi all,

    Sorry to reopen this issue but I still think there is a bug somewhere,
perhaps in the JDBC driver. The code and the end of this message
demonstrates the bug. Basically I write a timestamp to the database and then
read it back and  what I write and what I get back are different. I don't
see how I can progrmatically make this correct in a consistent way without
knowing the "magic" dates in Postgres. Note that I believe there are more
than just one magic date. Apparently at ever older date (around 10,000 BC I
believe) the seconds are dropped.
    The output from the code is (the computer's time was 03:23:49):

1850-Jan-01 03:23:49 JST
1850-Jan-01 06:23:49 JST

Thanks,

--Rainer
