Position, Velocity and Time
Is there a standard ROS message that can represent an object's x, y position along with its velocity at each position and time passed at the position?

That sounds a lot like a Trajectory specifically the MultiDOFJointTrajectory http://wiki.ros.org/trajectory_msgs
maybe this answer is what you're looking for?

It would be good if you could provide a little more details. Are you looking for something that can report current state, or something that is used to encode desired state?
This is for desired state. I'm trying to output points along a trajectory where each point represents x, y, desired velocity at that point, and the time to get to the point.
To encode desired state, a trajectory would seem to be the logical choice. That would be what @tfoote suggested. However, perhaps a nav_msgs/Path would be better suited than the
trajectory_msgs
he links to.
