+ *
+ * `throttleTime` emits the source Observable values on the output Observable
+ * when its internal timer is disabled, and ignores source values when the timer
+ * is enabled. Initially, the timer is disabled. As soon as the first source
+ * value arrives, it is forwarded to the output Observable, and then the timer
+ * is enabled. After `duration` milliseconds (or the time unit determined
+ * internally by the optional `scheduler`) has passed, the timer is disabled,
+ * and this process repeats for the next source value. Optionally takes a
+ * {@link IScheduler} for managing timers.
+ *
+ * @example <caption>Emit clicks at a rate of at most one click per second</caption>
+ * var clicks = Rx.Observable.fromEvent(document, 'click');
+ * var result = clicks.throttleTime(1000);
+ * result.subscribe(x => console.log(x));
+ *
+ * @see {@link auditTime}
+ * @see {@link debounceTime}
+ * @see {@link delay}
+ * @see {@link sampleTime}
+ * @see {@link throttle}
+ *
+ * @param {number} duration Time to wait before emitting another value after
+ * emitting the last value, measured in milliseconds or the time unit determined
+ * internally by the optional `scheduler`.
+ * @param {Scheduler} [scheduler=async] The {@link IScheduler} to use for
+ * managing the timers that handle the throttling.
+ * @return {Observable<T>} An Observable that performs the throttle operation to
+ * limit the rate of emissions from the source.
