I am creating some bagfiles to run BLAM offline with.
These bagfiles are captured by playing a pcap file from a VLP-16 over ROS and then using:
rosbag record velodyne_points
When running BLAM offline with these bagfiles, it consistently reports the final bagfile timestamp as 0.
As a result, it finishes processing immediately with the message "0 percent of real-time".
Originally, it only did this occasionally, and I would have to rerecord the bagfile, but now it seems to have this issue with every new bagfile I create.

rosbag info shows the timestamps are correct: path: 2019-09-03-14-49-55.bag version: 2.0 duration: 25.7s start: Sep 03 2019 14:50:00.25 (1567536600.25) end: Sep 03 2019 14:50:25.97 (1567536625.97) size: 108.8 MB messages: 256 compression: none [119/119 chunks] types: sensor_msgs/PointCloud2 [1158d486dd51d683ce2f1be655c3c181] topics: velodyne_points 256 msgs : sensor_msgs/PointCloud2
