When the artisan command php artisan responsive-images:convert is used with the --include-since option we don't need to convert it with strtotime since the Symfony\Component\Finder::date handles this.
The current implementation gives errors indicating that an invalid date is specified. This is because the date has already been converted to a time.
I hope I have explained sufficiently why I am offering this PR.
