LaserScan messages have invalid time_increment and scan_time values!

[pitosalas]

LaserScan messages (http://docs.ros.org/en/melodic/api/sensor_msgs/html/msg/LaserScan.html) has very invalid time_increment and scan_time values:

time_increment: 153333.328125
scan_time: 110400000.000000

This causes problems in the rest of the code, as well as rviz. Any idea on what might be causing this? I've traced the code and I can't see it. Thanks!
