Laravel seeding results in Null timestamp

Auto timestamp saving is only for Eloquent feature so you need to do manually like below for non eloquent feature

DB::table('languages')->insert([
    'name'        => 'English',
    'flag'        => '',
    'abbr'        => 'en',
    'script'    => 'Latn',
    'native'    => 'English',
    'active'    => '1',
    'default'    => '1',
    'created_at' => Carbon::now()->format('Y-m-d H:i:s'),
    'updated_at' => Carbon::now()->format('Y-m-d H:i:s')

]);

OR do it eloquently(Like you have seen in auto generated seeds like UserTableSeeder)

    $language = new Language();
    $language ->name = 'English';
    $language->flag'  = '',
    $language ->abbr  = 'en',
    $language->script ='Latn',
    $language->native ='English',
    $language->active ='1',
    $language->default ='1',
    $language->save();

Why to use carbon? Eloquent serves up Carbon for datetime and timestamp columns. By default it will serve up Carbon for the created_at, updated_at, and deleted_at columns. You can customize this in your models extending Eloquent\Model.

Carbon\Carbon extends \DateTime, so there is no loss of functionality by using Carbon in favor of DateTime, only more benefit/flexibility.

In users table seeder do this for timestamp. It works for me..

    use Carbon\Carbon;



    $faker = Factory::create();
    $date = Carbon::now()->modify('-2 year');
    $createdDate = clone($date);
    DB::table('users')->insert([

        [

            'name' => "XYZ",
            'slug' => "xyz",
            'email' => "[email protected]",
            'password' => bcrypt('secret'),
            'bio' => $faker->text(rand(250, 300)),
            'created_at' => $createdDate,
            'updated_at' => $createdDate

        ],
