Class DERGeneralizedTime

Implemented Interfaces:
DEREncodable, DERTags
public class DERGeneralizedTime
extends DERObject
Generalized time object.

APPLICATION, BIT_STRING, BMP_STRING, BOOLEAN, CONSTRUCTED, ENUMERATED, EXTERNAL, GENERALIZED_TIME, GENERAL_STRING, GRAPHIC_STRING, IA5_STRING, INTEGER, NULL, NUMERIC_STRING, OBJECT_IDENTIFIER, OCTET_STRING, PRINTABLE_STRING, SEQUENCE, SEQUENCE_OF, SET, SET_OF, T61_STRING, TAGGED, UNIVERSAL_STRING, UTC_TIME, UTF8_STRING, VIDEOTEX_STRING, VISIBLE_STRING

Constructor Summary

DERGeneralizedTime(Date time)
base constructer from a java.util.date object
DERGeneralizedTime(String time)
The correct format for this is YYYYMMDDHHMMSSZ, or without the Z for local time, or Z+-HHMM on the end, for difference between local time and UTC time.

Constructor Details

DERGeneralizedTime

public DERGeneralizedTime(Date time)
base constructer from a java.util.date object

DERGeneralizedTime

public DERGeneralizedTime(String time)
The correct format for this is YYYYMMDDHHMMSSZ, or without the Z for local time, or Z+-HHMM on the end, for difference between local time and UTC time.

Parameters:
time - the time string.

Method Details

equals

public boolean equals(Object o)
Overrides:
equals in interface DERObject

getDate

public Date getDate()
            throws ParseException

getInstance

public static DERGeneralizedTime getInstance(Object obj)
return a generalized time from the passed in object

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.

getTime

public 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.

hashCode

public int hashCode()
Overrides:
hashCode in interface DERObject
