/**
 * Class DateTimeAtCompleted is a printing attribute class, a date-time
 * attribute, that indicates the date and time at which the Print Job completed
 * (or was canceled or aborted).
 * <P>
 * To construct a DateTimeAtCompleted attribute from separate values of the
 * year, month, day, hour, minute, and so on, use a {@link java.util.Calendar
 * Calendar} object to construct a {@link java.util.Date Date} object, then use
 * the {@link java.util.Date Date} object to construct the DateTimeAtCompleted
 * attribute. To convert a DateTimeAtCompleted attribute to separate values of
 * the year, month, day, hour, minute, and so on, create a {@link
 * java.util.Calendar Calendar} object and set it to the {@link java.util.Date
 * Date} from the DateTimeAtCompleted attribute.
 * <P>
 * <B>IPP Compatibility: The information needed to construct an IPP
 * "date-time-at-completed" attribute can be obtained as described above. The
 * category name returned by <CODE>getName() gives the IPP attribute
 * name.
 * <P>
