| DateUtil | | abstract public class DateUtil (Code) | | Utility class supplying static methods. Date serialization is based on the
algorithms published by Peter Baum (http://www.capecod.net/~pbaum). All
date handling is done according to the W3C Schema specification, which uses
a proleptic Gregorian calendar with no year 0. Note that this differs from
the Java date handling, which uses a discontinuous Gregorian calendar.
