15  * Class DateTimeAtProcessing is a printing attribute class, a date-time
16  * attribute, that indicates the date and time at which the Print Job first
17  * began processing.
18  * <P>
19  * To construct a DateTimeAtProcessing attribute from separate values of the
20  * year, month, day, hour, minute, and so on, use a {@link java.util.Calendar
21  * Calendar} object to construct a {@link java.util.Date Date} object, then use
22  * the {@link java.util.Date Date} object to construct the DateTimeAtProcessing
23  * attribute. To convert a DateTimeAtProcessing attribute to separate values of
24  * the year, month, day, hour, minute, and so on, create a {@link
25  * java.util.Calendar Calendar} object and set it to the {@link java.util.Date
26  * Date} from the DateTimeAtProcessing attribute.
27  * <P>
28  * <B>IPP Compatibility:</B> The information needed to construct an IPP
29  * "date-time-at-processing" attribute can be obtained as described above. The
30  * category name returned by <CODE>getName()</CODE> gives the IPP attribute
31  * name.
