午夜後不啓動計時器

Question

我有兩個計時器。然後每5分鐘運行一次，另一次運行10分鐘。一旦我運行該應用程序它可以很好地工作，但在11:50之後它會停止執行。

我的代碼如下：

//At minute 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, and 55 past every hour from 0 through 4 and every hour. 

for(int hrsTime=1;hrsTime<=4;hrsTime++){ 
    System.out.println("hours start time : "+hrsTime); 
    _log.info("MrkRomeFiles hours start time : "+hrsTime); 
    start_1=0; 
    for(int i=0;i<11;i++){ 
     Calendar today = Calendar.getInstance(); 
     today.set(Calendar.HOUR_OF_DAY, hrsTime);//everyday 1,2,3 and 4 oclock 
     today.set(Calendar.MINUTE, start_1); 
     today.set(Calendar.SECOND, 0); 
     timer.schedule(new MrkRomeFiles(_env), today.getTime(), TimeUnit.MILLISECONDS.convert(1, TimeUnit.DAYS));      

     System.out.println("minuts start time : "+start_1);     
     _log.info("MrkRomeFiles minuts start time : "+start_1); 

     start_1=start_1+5; 
    } 
}  

//At minute 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, and 55 past every hour from 8 through 23 every hour. 
for(int startTime=8;startTime<=23;startTime++){ 
    int start=0; 
    System.out.println("hours start time : "+startTime); 
    _log.info("MrkRomeFiles hours start time : "+startTime); 
    for(int i=0;i<11;i++){       
     System.out.println("minuts start time : "+start);      
     _log.info("MrkRomeFiles minuts start time : "+start); 
     Calendar today = Calendar.getInstance(); 
     today.set(Calendar.HOUR_OF_DAY, startTime); 
     today.set(Calendar.MINUTE, start); 
     today.set(Calendar.SECOND, 0);      
     timer.schedule(new MrkRomeFiles(_env), today.getTime(), TimeUnit.MILLISECONDS.convert(1, TimeUnit.DAYS)); 
     start=start+5; 
    } 
} 

//this is for run every 10min 
for(int startTime=0;startTime<=23;startTime++){ 
    _log.info("oracle hour time : : "+startTime); 
    System.out.println("oracle hour time : "+startTime); 
    int startOraMinutes=0; 
     for(int i=0;i<6;i++){ 
      Calendar today = Calendar.getInstance(); 
      today.set(Calendar.HOUR_OF_DAY, startTime); 
      today.set(Calendar.MINUTE, startOraMinutes); 
      today.set(Calendar.SECOND, 0); 
      timer.schedule(new MrkOraFiles(_env), today.getTime(), TimeUnit.MILLISECONDS.convert(1, TimeUnit.DAYS)); 

      _log.info("oracle minuts time : "+startOraMinutes); 
      System.out.println("oracle minuts time : "+startOraMinutes); 
      startOraMinutes=startOraMinutes+10; 
      } 
     } 

低於是其上印有日誌：

爲什麼你不能簡單地安排您的任務，每5/10分鐘？

Timer timer = new Timer(); 
    TimerTask task = new TimerTask(){ 
     @Override 
     public void run(){ 
      System.out.println(System.nanoTime()); 
     } 
    }; 

    Calendar today = Calendar.getInstance(); 
    today.set(Calendar.MINUTE, 0); 
    today.set(Calendar.SECOND, 0); 
    timer.scheduleAtFixedRate(task, today.getTime(), TimeUnit.MILLISECONDS.convert(5, TimeUnit.MINUTES));
