times — write process 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.1‐2008, Chapter 13, Headers) as returned by times(): tms_utime, tms_stime, tms_cutime, and tms_cstime, respectively.

Asynchronous Events
