The rtems_timer_get_information() call does most of this.
Is it what you want?

      the_info->the_class  = the_timer->the_class;
       the_info->initial    = the_timer->Ticker.initial;
       the_info->start_time = the_timer->Ticker.start_time;
       the_info->stop_time  = the_timer->Ticker.stop_time;

Or that someone forgot to document it. :)

Please submit a patch for the documentation.

If it doesn't do what you want, submit a patch.  The info
calls are always an evolving thing.
