Digital Signature set custom SignedDate property instead of pc (Now)

[Jacobs]

Hello,

I have an issue that the SignedDate is automatically taken from client pc , so if client manipulated his pc time and i am using timestamp server ... i get two dates ... one from his pc in PdfSignature.SignedDate and one from timestampserver in PdfSignatureValidationResult.TimeStampInformation.Time

so if you can add set method to this property "SignedDate", as it causes conflict when using timestamp server,

if this property is not set in code, then it should be set automatically in library like the current behaviour.

Or another suggestion , if a timestampserver is used you can set both fields with same value of timestamptime.

Thanks , but is there any workaround ... if you can set signeddate with timestamptime in case of using timestampserver while signing to avoid the conflict ... Note that the Signed data property can be set in other libraries like iText
