Java里如何得到00:00:00格式的时分秒的Timestamp

import java.sql.Timestamp; import java.text.SimpleDateFormat; import java.util.TimeZone; public class Test { public static void main(String[] args) { SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); long t = System.currentTimeMillis(); t = t / (1000 * 3600 * 24) * (1000 * 3600 * 24); System.out.println(sdf.format(new Timestamp(t))); t = System.currentTimeMillis(); t = t / (1000 * 3600 * 24) * (1000 * 3600 * 24) - TimeZone.getDefault().getRawOffset(); System.out.println(sdf.format(new Timestamp(t))); } }

如果不扣掉时区偏移，那么时间将是北京默认的东8区(GMT+8)
