Function Documentation

resolveHourAmbiguity()

ros::Time resolveHourAmbiguity	(	const ros::Time &	stamp,
		const ros::Time &	nominal_stamp
	)

Function used to check that hour assigned to timestamp in conversion is correct. Velodyne only returns time since the top of the hour, so if the computer clock and the velodyne clock (gps-synchronized) are a little off, there is a chance the wrong hour may be associated with the timestamp.

Parameters

stamp	timestamp recovered from velodyne
nominal_stamp	time coming from computer's clock

Returns

timestamp from velodyne, possibly shifted by 1 hour if the function arguments disagree by more than a half-hour.
