Hi Bruno,
Patric has already explained Barbour's position (I didn't read his book).
Separating space from time is not very natural...
Perhaps one can use a similar method as presented here:
http://arxiv.org/abs/math-ph/0008018
to derive the notion of space-time as a first person phenomena.

Indeed. (SGrz pour those who knows). I would like to know if Norman and
Saibal and others agree that there is nothing special with time. Why
does not Julian Barbour talk about space-time capsule? (Or does he?)
I think space is also a first person phenomena. OK?
