Gorm type标签无法指定time类型？

通过type标签指定At为Time类型：

type Test struct {
    At string `gorm:"type:time"`
}

但AutoMigrate时却使用了datetime类型：

[3.979ms] [rows:0] CREATE TABLE `tests` (`at` datetime(3) NULL)

临时解决方案：

db.AutoMigrate(&model.Test{})

db.Exec("alter table tests modify at time null")

望修复。

为了这个小问题再引入一个自定义类型的包我感觉是不合适的，因为本质上标签无法指定time类型这个问题并没有解决。

同时，date没问题，time却有问题，为什么不一致？

我认为应该从造成这种不一致的原因的地方去尝试解决。

type Test struct {
    Date time.Time `gorm:"type:date;not null"`
    Time time.Time `gorm:"type:time;not null"`
}

CREATE TABLE `tests` (`date` date NOT NULL,`time` datetime(3) NOT NULL)

Bug due to no distinction between gorm type time.Time and tag type:time https://github.com/go-gorm/mysql/blob/master/mysql.go#L356

These jobs are all the same :(

Or do we change schema.Time from "time" to "go_time"? The downside is that the old version of the drivers cannot work with the modified gorm
