### Constructor Summary

Constructors
Constructor and Description
`DERGeneralizedTime(java.util.Date time)` base constructer from a java.util.date object
`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.

### Method Summary

Methods
`java.util.Date` `getDate()`
`static DERGeneralizedTime` `getInstance(ASN1TaggedObject obj, boolean explicit)` return a Generalized Time object from a tagged object.
`static DERGeneralizedTime` `getInstance(java.lang.Object obj)` return a generalized time from the passed in object
`java.lang.String` `getTime()` return the time - always in the form of YYYYMMDDhhmmssGMT(+hh:mm|-hh:mm).
`java.lang.String` `getTimeString()` Return the 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`
