Although I was thinking more of Baxter's approach to the issues of time travel (e.g. avoiding paradoxes) - rather than the machinery involved. Wells didn't address that side of things to any great extent iirc.
I don't mind a novelist using a few conceits to get where they want to be in order to depict a hard SF narrative. It's what they do when they get there I find interesting. I'd say Rudy Rucker's 'White Light' was a hard SF exploration of abstruse (to me) mathematical concepts - even if he does use 'fuzz weed' to set things up.
