[Boost-users] [date_time] Formating a posix::time_duration

I have a racing time in miliseconds which I'd like to apply formatting to, I can't seem to get it to work using posix::time_duration and what I'd think is the appropriate time_facet ( it produces the same results as the default facet ). Looking at posix_time_io.hpp I see the following comment: "// todo fix to use facet -- place holder for now...", leading me to believe that there's perhaps no way to apply the formating strings to a time_duration yet? We want to present our times as MM:SS,FFF.
