public abstract class DateTimeSyntax extends Object implements Serializable, Cloneable
Class DateTimeSyntax is an abstract base class providing the common implementation of all attributes whose value is a date and time.

Under the hood, a date-time attribute is stored as a value of class java.util.Date. You can get a date-time attribute's Date value by calling getValue(). A date-time attribute's Date value is established when it is constructed (see DateTimeSyntax(Date)). Once constructed, a date-time attribute's value is immutable.

To construct a date-time attribute from separate values of the year, month, day, hour, minute, and so on, use a java.util.Calendar object to construct a java.util.Date object, then use the java.util.Date object to construct the date-time attribute. To convert a date-time attribute to separate values of the year, month, day, hour, minute, and so on, create a java.util.Calendar object and set it to the java.util.Date from the date-time attribute. Class DateTimeSyntax stores its value in the form of a java.util.Date rather than a java.util.Calendar because it typically takes less memory to store and less time to compare a java.util.Date than a java.util.Calendar.
