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
