The date and time of signing
This represents the date and time of signing as specified in the signature. For signatures that contain a time-stamp, the trusted time-stamp time is returned.
Note: The value can only be extracted for signatures conforming to the PAdES or PDF standard and not for proprietary/non-standard signature formats. For non-standard signature formats the date as stored in the PDF is returned.
