JAVA获取当前系统时间（包含时分秒）插入数据库

网上找到好多方法，但是貌似都是不准确，当我看到这个我内牛满面

Timestamp d= new Timestamp(System.currentTimeMillis());

//获取系统时间直接转换成yy--mm-dd HH:mm:ss 形式

下面是一个例子

package com.test.jdbc;

import java.sql.Connection;  
import java.sql.DriverManager;  
import java.sql.PreparedStatement;  
import java.sql.ResultSet;  
import java.sql.Timestamp;

public class Connect \{  
private static final String DRIVER = "com.mysql.jdbc.Driver";  
private static final String IP = "jdbc:mysql://127.0.0.1:3306/msdn";  
private static final String user = "root";  
private static final String password = "";

public static void main(String args\[\]) throws Exception \{

Connection conn = null;  
  PreparedStatement pstmt = null;  
  Timestamp d = new Timestamp(System.currentTimeMillis());  
  String sql = "insert into user(name,password,age,sex,birthday) values(?,?,?,?,?) ";

Class.forName(DRIVER);  
  conn = DriverManager.getConnection(IP, user, password);  
  pstmt = conn.prepareStatement(sql);  
  pstmt.setString(1, "zl");  
  pstmt.setString(2, "123456");  
  pstmt.setInt(3, 24);  
  pstmt.setString(4, "man");  
  pstmt.setTimestamp(5, d);

pstmt.executeUpdate();  
  pstmt.close();  
  conn.close();

\}  
\}
