public class ASN1GeneralizedTime

extends ASN1Time

This is the Generalized Time class. In principle, the known time types are all of type VisibleString. GeneralizedTime is defined as [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.

Constructor Detail

ASN1GeneralizedTime

public ASN1GeneralizedTime()

Creates an instance. The value of this instance is set to the current date.

ASN1GeneralizedTime

public ASN1GeneralizedTime(String time)

Creates an instance with the given date string. The date string must be well-formed according to the BER.

Parameters:

time - The string representation of the date.

Throws:

IllegalArgumentException - if the given string has a bad format.

StringIndexOutOfBoundsException - if the string is not well-formed.

ASN1GeneralizedTime

public ASN1GeneralizedTime(Calendar cal)

Creates an instance with the given date.

Parameters:

cal - The Calendar.

ASN1GeneralizedTime

public ASN1GeneralizedTime(Date date)

Creates an instance with the given date.

Parameters:

date - The date.

ASN1GeneralizedTime

public ASN1GeneralizedTime(long time)

Creates an instance with the given number of milliseconds since January 1, 1970, 00:00:00 GMT.

Parameters:

time - The time.
