Do we have a TimeSpan sort of class in Java

I was just wondering if there is a need of TimeSpan in java.util so that I can define how much hours,minutes and seconds are there in between these two times.

From this TimeSpan we can have a time interval between two times. like

TimeSpan getTimeSpan( Date before, Date after ){...}

or

long timeSpan = System.currentTimeMillis();
// ... long job
timeSpan = System.currentTimeMillis() - timeSpan;

TimeSpan ts = new TimeSpan(timeSpan);

and with this TimeSpan we can use it in SimpleDateFormat.

SimpleDateFormat format = new SimpleDateFormat("HH:mm:ss");
format.format( timsSpan );

I am not sure if this is already been implemented in Java but yet undiscovered by me.
