            Duration

Duration represents the ROS 'duration' primitive, which consists of two integers: seconds and nanoseconds. The Duration class allows you to add and subtract Duration instances, including adding and subtracting from Time instances.

Instance Methods

__init__(self, secs=0, nsecs=0)
Create new Duration instance.
