<a name="id1110675"></a><h2>Description</h2>
<p>A high precision clock that measures the local time at a resolution up to microseconds and adjusts to the resolution of the time system. For example, for the a library configuration with nano second resolution, the last 3 places of the fractional seconds will always be 000 since there are 1000 nano-seconds in a micro second. </p>
