+/**
+ * Attaches a timestamp to each item emitted by an observable indicating when it was emitted
+ *
+ * The `timestamp` operator maps the *source* observable stream to an object of type
+ * `{value: T, timestamp: R}`. The properties are generically typed. The `value` property contains the value
+ * and type of the *source* observable. The `timestamp` is generated by the schedulers `now` function. By
+ * default it uses the *async* scheduler which simply returns `Date.now()` (milliseconds since 1970/01/01
+ * 00:00:00:000) and therefore is of type `number`.
+ *
+ * ![](timestamp.png)
+ *
+ * ## Example
+ *
+ * In this example there is a timestamp attached to the documents click event.
+ *
+ * ```ts
+ * import { fromEvent } from 'rxjs';
+ * import { timestamp } from 'rxjs/operators';
+ *
+ * const clickWithTimestamp = fromEvent(document, 'click').pipe(
+ *   timestamp()
+ * );
+ *
+ * // Emits data of type {value: MouseEvent, timestamp: number}
+ * clickWithTimestamp.subscribe(data => {
+ *   console.log(data);
+ * });
+ * ```
+ *
+ * @param scheduler
+ * @return {Observable<Timestamp<any>>|WebSocketSubject<T>|Observable<T>}
+ * @method timestamp
+ * @owner Observable
+ */
+export function timestamp<T>(scheduler: SchedulerLike = async): OperatorFunction<T, Timestamp<T>> {
+  return map((value: T) => new Timestamp(value, scheduler.now()));
+  // return (source: Observable<T>) => source.lift(new TimestampOperator(scheduler));
+}
+
+export class Timestamp<T> implements TimestampInterface<T> {
+  constructor(public value: T, public timestamp: number) {
