PHP warning messages on checkout after update to 1.3.9

The latest update to version 1.3.9 fixed many bugs and gives perfect timing selection based on the timezone set. Unfortunately it introduces a small bug, on the checkout page the plugin gives PHP warnings:

Warning: DateTime::setTime() expects at most 3 parameters, 4 given in /home4/aayushkapoor/public_html/wp-content/plugins/woocommerce-local-pickup-time-select/public/class-local-pickup-time.php on line 464

The reason is because setTime() only accepts max 3 params of H:M:S

For existing users, I fixed it by modifying line 464 in the file :
From $pickup_datetime->setTime( 0, 0, 0, 0 );
to $pickup_datetime->setTime( 0, 0, 0);

I hope you fix it in the future release as its very annoying. But thanks for this great plugin.

Thanks and Regards,
