DateTime paramDateTime = DateTime.Now;//如果paramGetDate==null，则使用当前时间 if (dateTime > 0) { //将long类型时间戳的参数转换为DateTime类型 paramDateTime = new DateTime(1970, 1, 1).AddMilliseconds(dateTime); }
TimeSpan ts = DateTime.Now - new DateTime(1970, 1, 1);
ts.TotalMilliseconds
原来Java的日期添加不像.NET的.Add；
import java.util.Date ;
date=new date();//取时间
Calendar calendar = new GregorianCalendar();
calendar.setTime(date);
calendar.add(calendar.DATE,1);//把日期往后增加一天.整数往后推,负数往前移动
//增加1秒 calendar.add (Calendar.SECOND, 1);
date=calendar.getTime(); //这个时间就是日期往后推一天的结果
------
毫秒 long类型 处理方法
使用Calendar的setTimeInMillis的方法，注意c.add(Calendar.MILLISECOND,int value)并不能完成任务.
示范代码如下：
Calendar c = Calendar.getInstance();
c.setTimeInMillis(1403931367000L);
System.out.println(c.getTime());

jquery：
new Date().getTime()//获取当前时间(从1970.1.1开始的毫秒数)
new Data(具体时间点).getTime()
