## Class DateTimeAtCreation

- java.lang.Object
- - javax.print.attribute.DateTimeSyntax
  - - javax.print.attribute.standard.DateTimeAtCreation

- All Implemented Interfaces:
    Serializable, Cloneable, Attribute, PrintJobAttribute

      public final class DateTimeAtCreation
      extends DateTimeSyntax
      implements PrintJobAttribute

  Class DateTimeAtCreation is a printing attribute class, a date-time attribute, that indicates the date and time at which the Print Job was created.

  To construct a DateTimeAtCreation attribute from separate values of the year, month, day, hour, minute, and so on, use a `Calendar` object to construct a `Date` object, then use the `Date` object to construct the DateTimeAtCreation attribute. To convert a DateTimeAtCreation attribute to separate values of the year, month, day, hour, minute, and so on, create a `Calendar` object and set it to the `Date` from the DateTimeAtCreation attribute.

  IPP Compatibility: The information needed to construct an IPP "date-time-at-creation" attribute can be obtained as described above. The category name returned by `getName()` gives the IPP attribute name.

    - #### equals

          public boolean equals(Object object)

      Returns whether this date-time at creation attribute is equivalent to the passed in object. To be equivalent, all of the following conditions must be true:
      1. `object` is not null.
      2. `object` is an instance of class DateTimeAtCreation.
      3. This date-time at creation attribute's `Date` value and `object`'s `Date` value are equal.
      Overrides:
        `equals` in class `DateTimeSyntax`
      Parameters:
        `object` - Object to compare to.
      Returns:
        True if `object` is equivalent to this date-time at creation attribute, false otherwise.
