SYNOPSIS         top

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,
       respectively.
