Serialization error on update

Update with serializer:unixtime does not insert timestamps properly

Description

Here's my code, the database mysql:8.0.0 field is the timestamp type. If I don't specify serializer:unixtime, I can't plug in. There is no problem with Create after using it. But you can't call the update, here's the SQL that you get after the code runs

package main

import (
	"fmt"
	"gorm.io/driver/mysql"
	"gorm.io/gorm"
)

type BaseModel struct {
	Updated int64 `gorm:"autoUpdateTime;serializer:unixtime"` // Use unix MILLI seconds as updating time
	Created int64 `gorm:"autoCreateTime;serializer:unixtime"` // Use unix seconds as creating time
}

func main() {

	dsn := "root:123456@tcp(127.0.0.1:3306)/?charset=utf8mb4&parseTime=True&loc=Local"
	db, err := gorm.Open(mysql.Open(dsn), &gorm.Config{})
	if err != nil {
		panic(err)
	}
	createSql := db.ToSQL(func(tx *gorm.DB) *gorm.DB {
		return tx.Create(&BaseModel{})
	})
	fmt.Println("createSql", createSql)
	updateSql := db.ToSQL(func(tx *gorm.DB) *gorm.DB {
		return tx.Updates(&BaseModel{})
	})

	fmt.Println("updateSql", updateSql)
}

Here are the results

createSql INSERT INTO `base_models` (`updated`,`created`) VALUES ('2024-04-29 16:03:24','2024-04-29 16:03:24')

2024/04/30 00:03:24 E:/demo/main.go:26 WHERE conditions required
updateSql UPDATE `base_models` SET `updated`=1714406604

Try this:

type BaseModel struct {
	Updated int64 `gorm:"autoUpdateTime;serializer:unixtime"` 
	Created int64 `gorm:"autoCreateTime;serializer:unixtime;default:CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP"`
