Class ASN1GeneralizedTime

java.lang.Object

org.bouncycastle.asn1.ASN1Object

org.bouncycastle.asn1.ASN1Primitive

org.bouncycastle.asn1.ASN1GeneralizedTime

All Implemented Interfaces:

ASN1Encodable, Encodable

Direct Known Subclasses:

DERGeneralizedTime

public class ASN1GeneralizedTime
extends ASN1Primitive

Base class representing the ASN.1 GeneralizedTime type.

The main difference between these and UTC time is a 4 digit year.

Constructor Summary

Constructors

Constructor and Description
ASN1GeneralizedTime(java.util.Date time) Base constructor from a java.util.date object
ASN1GeneralizedTime(java.util.Date time, java.util.Locale locale) Base constructor from a java.util.date and Locale - you may need to use this if the default locale doesn't use a Gregorian calender so that the GeneralizedTime produced is compatible with other ASN.1 implementations.
ASN1GeneralizedTime(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.

Constructor Detail

ASN1GeneralizedTime

public ASN1GeneralizedTime(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.

ASN1GeneralizedTime

public ASN1GeneralizedTime(java.util.Date time)

Base constructor from a java.util.date object

Parameters:

time - a date object representing the time of interest.

ASN1GeneralizedTime

public ASN1GeneralizedTime(java.util.Date time,
                   java.util.Locale locale)

Base constructor from a java.util.date and Locale - you may need to use this if the default locale doesn't use a Gregorian calender so that the GeneralizedTime produced is compatible with other ASN.1 implementations.

Parameters:

time - a date object representing the time of interest.

locale - an appropriate Locale for producing an ASN.1 GeneralizedTime value.

Method Detail

getInstance

public static ASN1GeneralizedTime getInstance(java.lang.Object obj)

return a generalized time from the passed in object

Parameters:

obj - an ASN1GeneralizedTime or an object that can be converted into one.

Returns:

an ASN1GeneralizedTime instance, or null.

Throws:

java.lang.IllegalArgumentException - if the object cannot be converted.

getInstance

public static ASN1GeneralizedTime 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.

Returns:

an ASN1GeneralizedTime instance.

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.

Returns:

a String representation of the time.

getDate

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

Throws:

java.text.ParseException

hashCode

public int hashCode()

Specified by:

hashCode in class ASN1Primitive
