The authors study cubic differential systems having an isochronous center and an inverse integrating factor formed by two different parallel straight lines. They have found nine subclasses of such time-reversible systems. The authors also prove that time-reversible polynomial differential systems with a nondegenerate center have half of the isochronous constant equal to zero and present two open problems.
