    <title>Performance</title>
    <para>
      Between a <link linkend="clockon"><citetitle>clockon</citetitle></link> and a <emphasis>clockoff</emphasis> opcode, the CPU time used is accumulated in the clock.  The precision is machine dependent but is the millisecond range on UNIX and Windows systems. The <link linkend="readclock"><citetitle>readclock</citetitle></link> opcode reads the current value of a clock at initialization time.
    </para>
