        <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.
