newbie question to setTimestamp( int parameterIndex, Timestamp x, Calendar cal) - Mailing list pgsql-jdbc

Hi all!

I am new to postgresql and i have the following question:

how does setTimestamp( int parameterIndex, Timestamp x, Calendar cal) work?
why is there a parameter Timestamp? I have a Calendar in my java code and I
would like to store it in the database via a PreparedStatement. So for
example:

I have the following table:

CREATE TABLE dates( date    TIMESTAMP WITH TIME ZONE );

Java code:

PreparedStatement ps = connection.prepareStatement( "INSERT INTO
    dates (date) VALUES ?");
ps.setTimestamp( 1, new Timestamp(), myCalendar );

Is this correct? But why is there a Timestamp parameter? It seems clear that
the
calendar should be converted into a timestamp because the method is named
setTimestamp. I am really confused about this.

Please help

Peter
