      • DERGeneralizedTime

        public DERGeneralizedTime​(java.lang.String time)
        The correct format for this is YYYYMMDDHHMMSS[.f]Z, or without the Z for local time, or Z+-HHMM on the end, for difference between local time and UTC time. The fractional second amount f must consist of at least one number with trailing zeroes removed.
        Parameters:
        time - the time string.
        Throws:
        java.lang.IllegalArgumentException - if String is an illegal format.

        public DERGeneralizedTime​(java.util.Date time)

    • Method Detail

      • getInstance

        public static DERGeneralizedTime getInstance​(java.lang.Object obj)
        return a generalized time from the passed in object
        Throws:
        java.lang.IllegalArgumentException - if the object cannot be converted.
      • getInstance

        public static DERGeneralizedTime getInstance​(ASN1TaggedObject obj,
                                                     boolean explicit)
        return a Generalized Time object from a tagged object.
        Parameters:
        obj - the tagged object holding the object we want
        explicit - true if the object is meant to be explicitly tagged false otherwise.
        Throws:
        java.lang.IllegalArgumentException - if the tagged object cannot be converted.
      • getTimeString

        public java.lang.String getTimeString()
        Return the time.
        Returns:
        The time string as it appeared in the encoded object.
      • getTime

        public java.lang.String getTime()
        return the time - always in the form of YYYYMMDDhhmmssGMT(+hh:mm|-hh:mm).

        Normally in a certificate we would expect "Z" rather than "GMT", however adding the "GMT" means we can just use:

             dateF = new SimpleDateFormat("yyyyMMddHHmmssz");
         
        To read in the time and get a date which is compatible with our local time zone.
