@Override

    Instant startTime = currentTime;  // TODO make this from config

    // truncate to seconds
    Instant truncated = Instant.ofEpochSecond(currentTime.getEpochSecond());
    if (truncated.equals(currentTime)) {
        // in this particular case, minus 1 second to include this currentTime
        // because Predictor doesn't include this time at "next"MatchingTime() method
        truncated = truncated.minusSeconds(1);
    }
    Instant lastTime = truncated.minusSeconds(delaySeconds);

    return nextScheduleTime(lastTime);

@Override

    Instant next = next(currentScheduleTime);
    Instant nextNext = next(next);
    long estimatedInterval = nextNext.getEpochSecond() - next.getEpochSecond();

    // get an aligned time that is before currentScheduleTime
    Instant before = currentScheduleTime.minusSeconds(estimatedInterval);
    do {
        before = before.minusSeconds(estimatedInterval);
    } while(!before.isBefore(currentScheduleTime));

    // before is before currentScheduleTime but not sure how many times before. calculate it.
    Instant nextOfBefore = next(before);
    while (nextOfBefore.isBefore(currentScheduleTime)) {
        before = nextOfBefore;
        nextOfBefore = next(before);
    }

    // nextOfBefore is same with currentScheduleTime or after currentScheduleTime. nextOfBefore is next of before. done.
    return ScheduleTime.of(before, before.plusSeconds(delaySeconds));
