Class DERUTCTime

public class DERUTCTime extends ASN1Object

UTC time object.

Constructor Summary
	DERUTCTime(String time) The correct format for this is YYMMDDHHMMSSZ (it used to be that seconds were never encoded.
	DERUTCTime(Date time) base constructer from a java.util.date object

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(Object obj) return an UTC Time from the passed in object.
static DERUTCTime	getInstance(ASN1TaggedObject obj, boolean explicit) return an UTC Time from a tagged object.
String	getTime() return the time - always in the form of YYMMDDhhmmssGMT(+hh:mm\|-hh:mm).
int	hashCode()
String	toString()

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

getAdjustedDate

public Date getAdjustedDate()

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.

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.

getDate

public Date getDate()

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.

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.

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.

hashCode

public int hashCode()

toString

public String toString()
