Time travel allows you to see the state of the network at a
	    given time, and even fast forward or rewind on the fly with
	    keyboard shortcuts (See the 'keyboard shortcuts' help
	    section).
	    Some features might not work perfectly with time travel, but
	    you should get a pretty good idea of what went on.
	    While we have more detailed data, time travel is limited to
	    five minute intervals by default for performance reasons.
