Get pdf meta data - Creationdate format?

a testing program hsa been implemented to get pdf meta data "creationdate" by using aspose.pdf.kit.dll, but i foung that "creationdate" as "STRING", and format as "12/4/2003 15:54:17" and sometimes as "D:20080706121417Z", why there has differenct format?


Thank you very much for considering Aspose.

Can you please share some sample file which returns the date in "12/4/2003 15:54:17" this format?
