>             Project: Beam
>          Issue Type: Improvement
>          Components: sdk-java-core
>            Reporter: Andy Xu
>            Priority: Minor
>
> We have accidentally created events with *wrong* timestamps in the future which are accepted by
> outputWithTimestamp(), but will fail at a later step:
> java.lang.IllegalStateException: Timer 472976-06-15T20:09:57.269Z is beyond end-of-time
>         at Preconditions.checkState(Preconditions.java:199)
>         at ReduceFnRunner.scheduleEndOfWindowOrGarbageCollectionTimer(ReduceFnRunner.java:1050)
> [...]
> Would it make sense to implement a check already at outputWithTimestamp() level to fail early?
