public class DateTimeType
A custom persister that is able to store the org.joda.time.DateTime class in the database as epoch-millis long integer. This is done with reflection so we don't have to introduce the dependency.
NOTE: Because this class uses reflection, you have to specify this using DatabaseField.dataType()
. It
won't be detected automatically.
