           _C_l_o_c_k returns the amount of CPU time (in microseconds) used
           since the first call to _c_l_o_c_k.  The time reported is the sum
           of the user and system times of the calling process and its
           terminated child processes for which it has executed _w_a_i_t(2)
           or _s_y_s_t_e_m(3S).

           The resolution of the clock is 1 millisecond on the Ridge
           32, 10 milliseconds on Western Electric 3B processors,
           16.667 milliseconds on Digital Equipment Corporation
           processors.

           The value returned by _c_l_o_c_k is defined in microseconds for
           compatibility with systems that have CPU clocks with much
           higher resolution.  Because of this, the value returned will
           wrap around after accumulating only 2147 seconds of CPU time
           (about 36 minutes).
