type foo struct {
    ID        int64              `gorm:"column:id"`
	CreatedAt formatime.Date `gorm:"column:created_at" json:"created_at"`
	UpdatedAt formatime.Timestamp `gorm:"column:updated_at" json:"updated_at"`
	DeletedAt formatime.CustomTime `gorm:"column:deleted_at" json:"deleted_at"`
}

func Test_json(t *testing.T) {
	b := foo{
		CreatedAt: formatime.NewDateNow(),
		UpdatedAt: formatime.NewTimestampNow(),
		DeletedAt: formatime.NewCustomTimeNow("Jan _2 15:04:05"),
	}

	text, err := json.Marshal(&b)
	if err != nil {
		t.Fatal(err)
	} else {
		log.Print(string(text))
	}
}

func Test_gorm(t *testing.T) {
	b := &foo{}
    	gorm.DB.First(b)
	text, err := json.Marshal(&b)
	if err != nil {
		t.Fatal(err)
	} else {
		log.Print(string(text))
