+Representation Of Time {#time-representation}
+======================
+
+The [[#remote-playback-protocol]] and the [[#streaming-protocol]] represent
+points of time and durations in terms of a [=time scale=]. A time
+scale is a common denominator for time values that allows values to be
+expressed as rational numbers without loss of precision. The [=time scale=] is
