scheduleAtFixedRateSkippingToLatest increases the cpu resouces to 95% on 1 hour time shift.

Below code :

private CronScheduler getCronSchedulerExecutor() {
        final ThreadFactory threadFactory = new ThreadFactoryBuilder()
                .setNameFormat("merged-config-%d")
                .setDaemon(true)
                .build();
        Duration syncPeriod = Duration.ofMillis(30_000L);
        CronSchedulerBuilder cronSchedulerBuilder = CronScheduler.newBuilder(syncPeriod);
        cronSchedulerBuilder.setThreadFactory(threadFactory);
        cronSchedulerBuilder.setThreadName("merged-config-refresher");
        return cronSchedulerBuilder.build();
    }

cronScheduler.scheduleAtFixedRateSkippingToLatest(1000, 1800, TimeUnit.MILLISECONDS, runTimeMillis -> {
            runJob(); // some execution
        });

I change the time to 1 hour past and it suddenly spikes the cpu after 30 secs (maybe because my syncPeriod is set to 30secs).
May I know where I am doing wrong ?
