I use the rosnode to process rosbag to create my database, and I would like to feed rosbag to this node again, but the node just don't work and have the error msgs,

Warning: TF_OLD_DATA ignoring data from the past for frame depth at time 727885 according to authority unknown_publisher
Possible reasons are listed at http://wiki.ros.org/tf/Errors%20explained

According to the link above http://wiki.ros.org/tf/Errors%20expla...: The fix for this is to send an Empty message the topic /reset_time. There is a button in rviz to do this.

But I dont find it in rviz, any help here?

The wiki message is somewhat unclear, especially out of context- /reset_time is only for simulators (maybe gazebo?) that support it, the rviz reset button only resets that instance of rviz http://wiki.ros.org/rviz/UserGuide#Time

The time panel also lets you reset the visualizer's internal time state -- this causes a reset of all the displays, as well as a reset of tf's internal cache of data.
