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.

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 wantexplicit
- 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.
