How to save time.Now() in mysql table, column name as created_at timestamp null.

I am getting error :

Error:Error 1292: Incorrect datetime value: '2017-08-05 19:06:14.190 +0000' for column 'created_at' at row 1

Code that is running it to save :-

At line no. 62 here ( https://github.com/fragmenta/fragmenta-cms/blob/master/src/pages/actions/setup.go#L62 )

It calls code user := users.New()

in Line no. 51 at file here ( https://github.com/fragmenta/fragmenta-cms/blob/master/src/users/query.go#L51 )

New() function is setup.

Which is like :-

func New() *User {
    user := &User{}
    user.CreatedAt = time.Now()
    user.UpdatedAt = time.Now()
    user.TableName = TableName
    user.KeyName = KeyName
    user.Status = status.Draft
    return user
}
