How to print Matlab's DURATION

Question

Matlab has recently introduced a new type—duration. So I can do something like:

>> d = datetime('12:10:00') - datetime('12:05:00')
d = 
   00:05:00
>> whos d
  Name      Size            Bytes  Class       Attributes
  d         1x1               128  duration  

Now I'd like to output a result of some calculation, which is of duration type, using fprintf. However duration is neither a number nor a string, nor does it have a method to create a string. What can I do to make fprintf accept it?

I am with Matlab 2014b.

You can use

>> d_char = char(d);
>> whos d_char
   Name        Size            Bytes  Class    Attributes

   d_char      1x8                16  char
