The transport bar contains a set of 5 clocks that show the current selection range and punch ranges.

Clicking on the punch range clocks will locate to either the beginning or end of the punch range. Similarly, clicking on the range clocks will locate to either the beginning or end of the current selection. In this screen shot there is no current selection range, so the selection clocks show an "off" state.

The In and Out buttons relate to the Punch range, and allow to use only one of the two punch boundaries, or both:

In only

Records from the In marker on, without a end boundary

Out only

Records untils the Out marker, without a beginning boundary

In only

Records only between the In and Out markers

Right clicking on any of the 5 clocks brings up a context menu allowing to change the type of time display between the 4 clock modes, and to copy the selected clock's time to the clipboard.
