XML: Read time properties of XAdES signature
If validation of signature and XAdES succeeded, you can read time properties, stored in XAdES. First, you can read signing time. To do this use TElXAdESVerifier.SigningTime property. Then, you can read time, stored in timestamps (if present) using *TimestampCount and *Timestamps properties (for example: SignatureTimestampCount and SignatureTimestamps properties).
Additionally, you can use TElXAdESVerifier.CertifiedSigningTime and LastArchivalTime properties. CertifiedSigningTime property returns the first of SignatureTimestamp, SigAndRefsTimestamp or ArchiveTimestamp timestamps, in other words the timestamp, which certifies creation of the signature (SignatureValue element). The LastArchivalTime property returns last ArchiveTimestamp.
