/**
* Ignores source values for `duration` milliseconds, then emits the most recent
* value from the source Observable, then repeats this process.
*
* <span class="informal">When it sees a source values, it ignores that plus
* the next ones for `duration` milliseconds, and then it emits the most recent
* value from the source.</span>

*
* `auditTime` is similar to `throttleTime`, but emits the last value from the
* silenced time window, instead of the first value. `auditTime` emits the most
* recent value from the source Observable on the output Observable as soon as
* its internal timer becomes disabled, and ignores source values while the
* timer is enabled. Initially, the timer is disabled. As soon as the first
* source value arrives, the timer is enabled. After `duration` milliseconds (or
* the time unit determined internally by the optional `scheduler`) has passed,
* the timer is disabled, then the most recent source value is emitted on the
* output Observable, 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.auditTime(1000);
* result.subscribe(x => console.log(x));
*
* @see {@link audit}
* @see {@link debounceTime}
* @see {@link delay}
* @see {@link sampleTime}
* @see {@link throttleTime}
*
* @param {number} duration Time to wait before emitting the most recent source
* 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 rate-limiting behavior.
* @return {Observable<T>} An Observable that performs rate-limiting of
* emissions from the source Observable.
