Like a Feynman diagram, perhaps? Space and time can emerge from a network
of events, of course - in for example the delightfully named "spin foam"
(physics can be so poetic sometimes). However the chains of events are
themselves unchanging, and hence effectively embedded in something, even if
only an abstract topological space. One doesn't need a "higher-order time"
in which these events interact in some sense, one only needs them plus the
links between them. So this is just another way of getting space-time from
an underlying block universe.

That would be the "snapshot" approach to space-time espoused by David
Deutsch in FoR, I assume. It allows the "appearance of space, time and
change" to emerge from something that has no intrinsic time built in.
(Hence it shows how we could recover space and time from something like the
Wheeler-deWitt equation, I guess.)
