+<p>
+During the combination process BNC is waiting for clock corrections input epoch by epoch.
+BNC drops whatever is received later than 'Wait for full clock epoch' seconds.
+A value of about 10 seconds is recommended, depending on the latency of the incoming streams
+and the delay acceptable to your real-time GNSS combination product.

 <p>
 Specify a combination sampling interval. Orbit and clock corrections will be produced following that interval.
-value of 10 sec may be an appropriate choice.
