Comment:

 My bad. maybe the documentation is not explicit enough that this is not
 supported.

 The reference states the possible customization points

 {{{
   protected:
     virtual ~time_point_units();
     virtual string_type do_get_epoch(system_clock) const=0;
     virtual string_type do_get_epoch(steady_clock) const=0;

 #if defined(BOOST_CHRONO_HAS_PROCESS_CLOCKS)
     virtual string_type do_get_epoch(process_real_cpu_clock) const=0;
     virtual string_type do_get_epoch(process_user_cpu_clock) const=0;
     virtual string_type do_get_epoch(process_system_cpu_clock) const=0;
     virtual string_type do_get_epoch(process_cpu_clock) const=0;
 #endif
 #if defined(BOOST_CHRONO_HAS_THREAD_CLOCK)
     virtual string_type do_get_epoch(thread_clock) const=0;
 #endif}}}

 I would need to type erase the clock in someway, but I don't know how the
 user could identify its clock.
