DESCRIPTION         top

       The times utility shall write the accumulated user and system
       times for the shell and for all of its child processes, in the
       following POSIX locale format:

           "%dm%fs %dm%fs\n%dm%fs %dm%fs\n", <shell user minutes>,
               <shell user seconds>, <shell system minutes>,
               <shell system seconds>, <children user minutes>,
               <children user seconds>, <children system minutes>,
               <children system seconds>

       The four pairs of times shall correspond to the members of the
       <sys/times.h> tms structure (defined in the Base Definitions
       volume of POSIX.1‐2017, Chapter 13, Headers) as returned by
       times(): tms_utime, tms_stime, tms_cutime, and tms_cstime,
