Timer作为JDK提供的util工具,不太适合作为周期调度任务,只适合简单的定时操作(按照一定时间频率出发任务),在java的领域解决方案中,Quartz无疑是翘楚. Timer的调度方法有: public void schedule(TimerTask task, long delay) { if (delay < 0) throw new IllegalArgumentException("Negative delay."); sched(task, System.curr
jsp页面根据当前时间和定义时间差计算动态倒计时http://www.jb51.net/article/74140.htm var maxtime =1000*60; //半个小时,按秒计算,自己调整! second=maxtime/1000; // 写一个方法,将秒数专为天数 var toDays = function(){ var s = second % 60; // 秒 var mi = (second - s) / 60 % 60; // 分钟
<script type="text/javascript"> var orign_time = 1496706400; var leftTime = Date.parse(new Date())/1000;//转化成秒 var maxTime = orign_time-leftTime; function CountDownTime() { if (maxTime >=0) { var days = parseInt(maxTime/60/60/ 24, 10);

In some applications exact time measurement methods are very important. 一些应用程序中精确的时间测量是非常重要的. The often used Windows API method GetTickCount() retrieves the number of milliseconds that have elapsed since the system was started, but the GetTickCount()
