rviz is one of the few things that will handle backward jumps in time, but
you need to have rosbag broadcasting on the /clock topic:
rosbag play --clock
rviz will then detect backwards jumps in time and reset itself accordingly.
You can also manually reset rviz's sense of time using the "Reset" button on
the Time panel.
