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:

    <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 IEEE Std 1003.1-2001, Chapter 13, Headers) as returned by times(): tms_utime, tms_stime, tms_cutime, and tms_cstime, respectively.
