When retrieving some sensor data acquired by the robot, it can be interesting to know the timestamp associated with that data. All robot sensor data events are timestamped on a monotonic clock, associated with the robot. The timestamps express a number of nanoseconds since a robot-related epoch, typically since the robot was booted. As such, these timestamps are not directly convertible to a human date. They can be used for interval timing or when using time related APIs on the robot.
Warning
Robot APIs expecting timestamps should not be fed with tablet-related timestamps, which have no meaning for the robot.
Following is a list of timestamped robot sensor data APIs:
The FreeFrame.update() API accepts a robot timestamp for publishing
timestamped Transforms, see API doc FreeFrame.
