That is showing you the position of your scrubber which is at the beginning of the timeline (00:00:00:00). If you move the scrubber to another position, that number will change.
In any position is presenting the same information.

Your screenshot is showing with the scrubber at the 00 position. Can you post another with the scrubber at a different position and the information displayed so we can see what you are seeing?
That is odd. On my Vegas Pro version that information is shown when I hover the cursor over a particular Keyframe. This seems to be referencing the first keyframe on your timeline. If you hover above another keyframe, does it change? If not, then this might be a bug that needs to be reported.
