Returns an Observable that drops items emitted by the source ObservableSource during a specified time window
(defined on a specified scheduler) before the source completes.

@param time
the length of the time window
@param unit
the time unit of {@code time}
@param scheduler
the scheduler used as the time source
@param delayError
if true, an exception signalled by the current Observable is delayed until the regular elements are consumed
by the downstream; if false, an exception is immediately signalled and all regular elements dropped
@param bufferSize
the hint about how many elements to expect to be skipped
@return an Observable that drops those items emitted by the source ObservableSource in a time window before the
source completes defined by {@code time} and {@code scheduler}
