Unlike a topic - a one way communication pattern where a node publishes information that can be consumed by one or more subscribers - a service is a request/response pattern where a client makes a request to a node providing the service and the service processes the request and generates a See also: ros::TimeBase API docs, ros::DurationBase API docs ROS has builtin time and duration primitive types, which roslib provides as the ros::Time and ros::Duration classes, respectively.
