JDBC Timestamp problem

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 !
