Java里得到00:00:00格式的时分秒的Timestamp

importjava.sql.Timestamp;
importjava.text.SimpleDateFormat;
importjava.util.TimeZone;
publicclassTest{
publicstaticvoidmain(String[]args){
SimpleDateFormatsdf=newSimpleDateFormat("yyyy-MM-ddHH:mm:ss");
longt=System.currentTimeMillis();
t=t/(1000*3600*24)*(1000*3600*24);
System.out.println(sdf.format(newTimestamp(t)));
t=System.currentTimeMillis();
t=t/(1000*3600*24)*(1000*3600*24)-TimeZone.getDefault().getRawOffset();
System.out.println(sdf.format(newTimestamp(t)));
}
}
