## Class template subsecond_duration

boost::date_time::subsecond_duration — Template for instantiating derived adjusting durations.

## Synopsis

    // In header: <boost/date_time/time_duration.hpp>

    template<typename base_duration, boost::int64_t frac_of_second>
    class subsecond_duration : public base_duration {
    public:
      // types
      typedef base_duration::impl_type   impl_type;
      typedef base_duration::traits_type traits_type;

      // construct/copy/destruct
      explicit subsecond_duration(boost::int64_t);

      // private member functions
       BOOST_STATIC_ASSERT_MSG((traits_type::ticks_per_second >=frac_of_second?traits_type::ticks_per_second%frac_of_second:frac_of_second%traits_type::ticks_per_second) = =0,
                               \"The base duration resolution must be a multiple of the subsecond duration resolution");
