PdfDate is the PDF date object.

PDF defines a standard date format. The PDF date format closely follows the format defined by the international standard ASN.1 (Abstract Syntax Notation One, defined in CCITT X.208 or ISO/IEC 8824). A date is a PdfString of the form:

(D:YYYYMMDDHHmmSSOHH'mm')

This object is described in the 'Portable Document Format Reference Manual version 1.3' section 7.2 (page 183-184)
