25*e13b1fa5SApple OSS Distributions<p>
26*e13b1fa5SApple OSS DistributionsThe <strong>clock_get_time</strong> function returns the current time
27*e13b1fa5SApple OSS Distributionskept by a clock.  The
28*e13b1fa5SApple OSS Distributionsvalue returned is a monotonically increasing value (unless tampered
29*e13b1fa5SApple OSS Distributionswith via the
30*e13b1fa5SApple OSS Distributions<strong>clock_set_time</strong> function).
31*e13b1fa5SApple OSS Distributions<h3>RETURN VALUES</h3>
