How can I “pretty print” a Duration in Java?

Question

Does anyone know of a Java library that can pretty print a number in milliseconds in the same way that C# does?

E.g., 123456 ms as a long would be printed as 4d1h3m5

I realize this might not fit your use case exactly, but PrettyTime might be useful here.

PrettyTime p = new PrettyTime();
System.out.println(p.format(new Date()));
//prints: “right now”

System.out.println(p.format(new Date(1000*60*10)));
//prints: “10 minutes from now”
