docs: Check if the event with a given timestamp has occurred, according to the timer.
  This implementation always returns true and updates current timer's time to the timestamp
  of the most distant future event.
  @param time Timestamp in milliseconds.
  @return Always returns true.
  @deprecated [REEF-1532] Prefer passing Time object instead of the numeric timestamp.
  Remove after release 0.16.
