Laravel: The useCurrent() & useCurrentOnUpdate()

When using timestamp() columns in Laravel Migrations, append the useCurrent() & useCurrentOnUpdate() to set timestamp columns default value to CURRENT_TIMESTAMP.

Schema::create('table', function (Blueprint $table) {  
     ....
     $table->timestamp('created_at')->useCurrent();
     $table->timestamp('updated_at')->useCurrentOnUpdate();     
});
