title: Java equivalent to C#'s TimeSpan
body: <p>Does Java have a data type that represents a period of time eg 34 seconds, 5 minutes etc.</p>
  
  <p>I've seen a few implementations of a TimeSpan that cover a Time period like from the 10th of December to the 11th of December.</p>
  
  <p>What I need is something like TimeSpan in C#.</p>
