Constructor Summary

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

Method Details

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.

getTimeString

public String getTimeString()
Return the time.
Returns:
The time string as it appeared in the encoded object.

hashCode

public int hashCode()
Overrides:
hashCode in interface ASN1Object
