I'm trying to get update & creation date of an exists User after save. But all time these values are 01/01/0001 00:00.

private void UserServiceSaved(IUserService sender, SaveEventArgs<IUser> e)
{
        IUser user = e.SavedEntities.FirstOrDefault();
        var uDate = user.UpdateDate;
        var cDate = user.CreateDate;
}

How can I save & get these values ?

-Thanks :)
