I.e., you were able to make an arbitrary packet be the packet at time
zero?

I am as sure as I can be that you're remembering incorrectly; I don't
remember Ethereal ever having that capability.

You can display packet time stamps as:

	1) absolute time stamps - those aren't settable unless you have
	   the power of Time Control:

	2) relative time stamps - those are relative to the beginning of
	   the capture, and, again, are settable only if you have the
	   power of Time Control;

	3) delta time stamps - those are relative to the previous
	   displayed packet.
