Examples of codec.asn1.ASN1GeneralizedTime

codec.asn1.DERDecoder
This is the Generalized Time class. In principle, the known time types are all of type VisibleString. GeneralizedTime is defined as [ {@link ASN1#TAG_GENERALIZEDTIME UNIVERSAL 24}] IMPLICIT VisibleString . This class automatically represents dates internally in a DER compliant format, and parses dates according to BER. The internal representation is not changed from BER to DER on decoding. This is to ensure that decoding and encoding restore bitwise identical encodings. @author Volker Roth @author Stefan Endler @version "$Id: ASN1GeneralizedTime.java,v 1.3 2007/08/11 18:21:50 sendler Exp $"
