Sure, it's easy:
tl.getBand(0).getCenterVisibleDate() will return the center of band 0.
If your other bands are sync'ed to each other then that's all you need.
Try adding this:
var topBand = tl.getBand(0);
topBand.addOnScrollListener( function(band) {
document.getElementById("output").innerHTML =
band.getCenterVisibleDate();
});
As the user scrolls the timline, the date at the center of band 0 will be
printed in the element with id="output"
You could easily write the date out to a cookie or ajax it back to the server.
