Abstract: Synchronously negotiating an object's creation time including identifying, by a first storage system among the two or more storage systems, a request to store a second updated version of the object; detecting, by the first storage system, a communications disruption among the two or more storage systems; and establishing, in dependence upon a local clock of the first storage system and a latest observed creation time associated with the object, a creation time for the second updated version of the object.

Abstract: An improved coupler for a tongue on a towed vehicle that attaches to a tow hook mounted on a towing vehicle to either pull the towed vehicle over a road or to pull the towed vehicle located on an elevated surface. The coupler includes an elongated tongue tube attached to the end of the tongue attached to the towed vehicle. Upper and lower rings are axially aligned and mounted or attached to the front surface of the tongue tube. The rings are spaced apart on the tongue tube to allow the towing vehicle to pull or push the towed vehicle over the same roadway or an elevated surface. Brackets are used between the tongue tube and the trailer tongue to prevent compression, collapse, and fore to aft or aft to fore movements. An adjustable jack is attached to the side of the tongue tube. An optional lid is provided over the top opening of the tongue tube that covers a storage compartment inside the tongue tube. An optional chock holder plate and a pair of compatible chocks may be placed inside the storage compartment.
