Hello,

I have an application that worked well woth Postgresql 6.5.

Now I am on 7.0, and I get this exception when I execute an
rs.getTimestamp("reftime"):

Bad Timestamp Format at 0 in 1970-01-01 01:26:56.99+01
        at
org.postgresql.jdbc1.ResultSet.getTimestamp(ResultSet.java:445)
        at
org.postgresql.jdbc1.ResultSet.getTimestamp(ResultSet.java:587)

Any idea of what it might be ?

Thank you very much !

it's the timezone part ("+01") that's causing the problems.  it's not
supposed to be there, hence the error in parsing the timestamp.  i've
had the problem before & here's the way i solved it:

 Timestamp expires =
Timestamp.valueOf(rs.getString("field_name").substring(0,19));

there might be a way to alter the output format of the date, but i don't
know how.  maybe peter can help us out there or have some sort of
official response.

Yes, there's been a lot of problems with timestamps, mainly where it was
getting confused with timezone/millisecond variations. 99% of these have been
fixed in the 7.1 driver.

(I say 99% as there is bound to be a senario we've missed out ;-) )
