Constructor Summary

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

DERUTCTime(String time)

Method Summary

Date	getAdjustedDate() return the time as an adjusted date in the range of 1950 - 2049.
String	getAdjustedTime() return a time string as an adjusted date with a 4 digit year.
Date	getDate() return the time as a date based on whatever a 2 digit year will return.
static DERUTCTime	getInstance(ASN1TaggedObject obj, boolean explicit) return an UTC Time from a tagged object.

Constructor Detail

DERUTCTime

public DERUTCTime(String time)

The correct format for this is YYMMDDHHMMSSZ (it used to be that seconds were never encoded. When you're creating one of these objects from scratch, that's what you want to use, otherwise we'll try to deal with whatever gets read from the input stream... (this is why the input format is different from the getTime() method output).

Parameters:

time - the time string.

DERUTCTime

public DERUTCTime(Date time)

base constructer from a java.util.date object

Method Detail

getInstance

public static DERUTCTime getInstance(Object obj)

return an UTC Time from the passed in object.

Throws:

IllegalArgumentException - if the object cannot be converted.

getInstance

public static DERUTCTime getInstance(ASN1TaggedObject obj,
                                     boolean explicit)

return an UTC Time 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:

IllegalArgumentException - if the tagged object cannot be converted.

getDate

public Date getDate()
             throws ParseException

return the time as a date based on whatever a 2 digit year will return. For standardised processing use getAdjustedDate().

Returns:

the resulting date

Throws:

ParseException - if the date string cannot be parsed.

getAdjustedDate

public Date getAdjustedDate()
                     throws ParseException

return the time as an adjusted date in the range of 1950 - 2049.

Returns:

a date in the range of 1950 to 2049.

Throws:

ParseException - if the date string cannot be parsed.

getTime

public String getTime()

return the time - always in the form of YYMMDDhhmmssGMT(+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("yyMMddHHmmssz");
 

To read in the time and get a date which is compatible with our local time zone.

Note: In some cases, due to the local date processing, this may lead to unexpected results. If you want to stick the normal convention of 1950 to 2049 use the getAdjustedTime() method.

getAdjustedTime

public String getAdjustedTime()

return a time string as an adjusted date with a 4 digit year. This goes in the range of 1950 - 2049.

hashCode

public int hashCode()

Specified by:

hashCode in class ASN1Object

toString

public String toString()

Overrides:

toString in class Object
