Minor Description
SqlTimestampConverter should produce a Date/Time as output, but it only produces
a time. SqlTimeConverter prints a simple time as expected.
Looking in the code SqlTimestampConverter::convertToString uses:
DateFormat format = DateFormat.getTimeInstance(dateFormat, locale);
when I think it should say:
DateFormat format = DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.SHORT, locale);
instead.
convertToObject would need a corresponding change to:
DateFormat format = DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.SHORT, locale);
