You'd have to rewrite every TCP packet that went past to remove the
timestamp options.  That seems pretty bogus.  It'd also be impossible
to do unless you were *certain* that packets only got out via the gateway.

Why not let the end systems make that determination?  It seems like
they'd have a better idea of round trip times, window sizes, etc.
