Knut Anders Hatlen updated DERBY-4810:

    Attachment: test.diff

Attaching a test case that demonstrates the difference.

Fails with:

1) testTrailingZeros(org.apache.derbyTesting.functionTests.tests.lang.DateTimeTest)junit.framework.AssertionFailedError:
Column value mismatch @ column '1', row 1:
    Expected: >2010-09-22 14:40:33.012<
    Found:    >2010-09-22 14:40:33.012000000<

> With the statement
> PreparedStatement.setTimestamp(int,Timestamp) and PreparedStatement.setTimestamp(int,Timestamp,Calendar)
don't agree on what to do with trailing zeros in the nanosecond component. The method that
doesn't take a Calendar argument, removes trailing zeros. The method that takes a Calendar
object appends zeros so that the nanosecond component always has nine digits. (Both methods
have a special case when nanoseconds is zero, and they agree on adding just a single zero
after the decimal point in that case.)
> The format used by PreparedStatement.setTimestamp(int,Timestamp) matches what java.sql.Timestamp.toString()
returns (in fact, it uses Timestamp.toString() internally to produce the string representation),
and I think it would be reasonable to use that format for both the methods.
