如何.Scan（）將MySQL TIMESTAMP值轉換爲time.Time變量？

我有這樣的Go代碼：如何.Scan（）將MySQL TIMESTAMP值轉換爲time.Time變量？

package main 

import (
    "fmt" 
    "database/sql" 
    _"github.com/go-sql-driver/mysql" 
    "time" 
) 

type User struct { 
    id     uint32 
    name    string 
    email    string 
    rating    uint8 
    subscription  uint8 
    date_registered  time.Time 
    online    string 
} 

// main entry point 
func main() { 
    // setup db connection 
    db, err := sql.Open("mysql", "user:@tcp(127.0.0.1:3306)/c9?parseTime=true") 
    if err != nil { 
     fmt.Println(err) 
    } 
    defer db.Close() 

    // query 
    rows, err := db.Query("SELECT * FROM users WHERE id = ?", 1) 
    if err != nil { 
     fmt.Println(err) 
    } 
    defer rows.Close() 

    usr := User{} 
    for rows.Next() { 
     err := rows.Scan(&usr.id, &usr.name, &usr.email, &usr.rating, &usr.subscription, &usr.date_registered, &usr.online) 
     if err != nil { 
      fmt.Println(err) 
     } 
    } 
    fmt.Println(usr) 
    err = rows.Err() 
    if err != nil { 
     fmt.Println(err) 
    } 
}

這是我從MySQL控制檯中看到：

mysql> describe users; 
+-----------------+---------------------+------+-----+-------------------+----------------+ 
| Field   | Type    | Null | Key | Default   | Extra   | 
+-----------------+---------------------+------+-----+-------------------+----------------+ 
| id    | int(10) unsigned | NO | PRI | NULL    | auto_increment | 
| name   | varchar(50)   | NO |  | NULL    |    | 
| email   | varchar(50)   | NO |  | NULL    |    | 
| rating   | tinyint(3) unsigned | YES |  | NULL    |    | 
| subscription | tinyint(3) unsigned | NO |  | 0     |    | 
| date_registered | timestamp   | NO |  | CURRENT_TIMESTAMP |    | 
| online   | char(1)    | NO |  | N     |    | 
+-----------------+---------------------+------+-----+-------------------+----------------+ 
7 rows in set (0.00 sec) 

mysql> SELECT * FROM users; 
+----+------------+-----------------------+--------+--------------+---------------------+--------+ 
| id | name  | email     | rating | subscription | date_registered  | online | 
+----+------------+-----------------------+--------+--------------+---------------------+--------+ 
| 1 | alakhazamm | [email protected] | NULL |   0 | 2014-10-28 15:37:44 | N  | 
+----+------------+-----------------------+--------+--------------+---------------------+--------+ 
1 row in set (0.00 sec)

.Scan()

後，fmt.Println(usr)打印

{1 alakhazamm [email protected] 0 0 {0 0 <nil>} }

的最後兩個字段的結構是錯誤的，但我不知道爲什麼。我試過在結構定義中使用date_registered string，但在.Scan()之後我得到一個空字符串。我也讀過驅動程序的文檔，?parseTime=true解析MySQL DATE和DATETIME值到time.Time，但他們沒有提到我目前正在使用的TIMESTAMP。

我錯過了一些重要的東西，還是圖書館的缺陷/缺失功能？
