Public Constructors

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.

public DERUTCTime (Date time)

base constructer from a java.util.date object

Public Methods

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.

public String getAdjustedTime ()

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

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.

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.

public static DERUTCTime getInstance (Object obj)

return an UTC Time from the passed in object.

Throws
IllegalArgumentException if the object cannot be converted.

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.
