Christian,
On looking at your output once more, if you're trying to insert a
string, "2001-11-11 11:11:11::timestamp" into a TIMESTAMP datatype, this
won't work.
That's why it's complaining about a typecast... this at least makes
logical sense to me.
You'd have to change the datatype to accept

Please spare us the rudeness while you're at it and just stick to the

ah I see, in my case is it $result:
$result = $dbh->prepare ( "SELECT neue_auktion ( ?, ?, ?, ?, ?, ?, ?, ? ) "
) or die "Vorbereitung nicht durchfuehrbar!\n";
$result->bind_param ( 1, $arg1 );

does not work, because putting quotes around the variable ("$system_zeit") does
*not* produce a string with quote marks in it. This is elementary Perl syntax. And it
is very easy to verify with a test program.
If you want quotes, use $dbh->quote() as I
->quote( $system_zeit ) . "::timestamp";

You should not interpolate variables into the SQL statement, especially
not when you work in a CGI environment (or similar). You are begging for
