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.

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
