Spring中CronTrigger提前触发线程执行问题咨询

我使用Spring Boot的ThreadPoolTaskScheduler结合CronTrigger实现任务调度，任务仅负责打印当前日期时间，代码如下：

public class MyCron {
    Logger logger = LoggerFactory.getLogger(MyCron);

    private final ThreadPoolTaskScheduler scheduler;
    private final CronTrigger cronTrigger;
    private ScheduledFuture<?> runnableTask;

    public MyCron(String cronEntry) {
        this.scheduler = new ThreadPoolTaskScheduler();
        this.scheduler.setPoolSize(10);
        this.scheduler.setThreadNamePrefix("MyCron-" + name + "-");
        this.scheduler.initialize();
        this.cronTrigger = new CronTrigger(cronEntry);
        runnableTask = scheduler.schedule(this::workerThread, cronTrigger);
    }
}

其中this::workerThread方法用于打印时间，但发现任务总是比指定时间提前执行。例如配置Cron表达式0 */5 * * * *和0 */7 * * * *时，日志显示任务均在分钟的59秒执行：

我配置的CronTrigger秒数为0，预期任务在整分的0秒执行，比如0 */5 * * * *应在18:05:00执行，实际却在18:04:59执行。当前使用的版本为Spring Boot v3.3.0、Spring v6.1.8。

该问题已影响业务逻辑：任务中执行的SQL查询包含where timestamp < current_timestamp()条件，因任务提前执行且运行速度快，导致条件未触发。

请问这是什么原因导致的？是否存在配置错误？
