com.facebook.presto.jdbc.internal.joda.time.DateTimeField
Defines the calculation engine for date and time fields. The interface defines a set of methods that manipulate a millisecond datetime with regards to a single field, such as monthOfYear or secondOfMinute.
This design is extensible so, if you wish, you can extract a different field from the milliseconds. A number of standard implementations are provided to assist. @author Guy Allard @author Stephen Colebourne @author Brian S O'Neill @since 1.0
