Constructor Detail

### 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.

### DERGeneralizedTime

    public DERGeneralizedTime(java.util.Date time)

  base constructer from a java.util.date object

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.

### getDate

    public java.util.Date getDate()
                           throws java.text.ParseException

  Throws:
    `java.text.ParseException`

### hashCode

    public int hashCode()

  Specified by:
    `hashCode` in class `ASN1Object`
