Java中进行转换

UNIX时间戳转换为日期

Date date =new Date();

SimpleDateFormat simpleDateFormat=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

System.out.println((simpleDateFormat.parse(simpleDateFormat.format(date))).getTime()/1000);

日期转换为UNIX时间戳

Long timestamp = Long.parseLong("1410318106")*1000;

String date = new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new java.util.Date(timestamp));   

System.out.println(date);
