<para>
The <function>pcntl_sigtimedwait</function> function operates in exactly
the same way as <function>pcntl_sigwaitinfo</function> except that it takes
two additional parameters, <parameter>seconds</parameter> and
<parameter>nanoseconds</parameter>, which enable an upper bound to be placed
on the time for which the script is suspended.
