Further discussions at Google indicate that it would be nice to make
more components optional. Can we have something like this:

      [[h*:]mm:]ss[.[d[c[m]]]  | s*[.d[c[m]]]

Examples:
    23  = 23 seconds
    23.2  = 23 sec, 1 decisec
    1:23.45   = 1 min, 23 sec, 45 centisec
    123.456  = 123 sec, 456 millisec

Cheers,
Silvia.
