PROLOG
       This manual page is part of the POSIX Programmer's Manual.  The OS
       implementation of this interface may differ (consult the corresponding
       OS manual page for details of OS behavior), or the interface may not be
       implemented on OS.

NAME
       times -- write process times

SYNOPSIS
       times

DESCRIPTION
       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.
