Again, no -- you could easily read the documentation, though or you can
go over to the uBlox Forum if you don't believe me.

I've posted that link, you might want to actually read it.  The only FTS
product is the LEA-M8F and you don't need or even want it.  For timing
the M8T is the one to use.

Stop thinking, read the docs.  The timemark functionality is there in
all these.  The EXTINx inputs may not be accessible or tied up doing
other things in particular models (some modules for instance have only
one of the internally two EXTINTx inputs available and may already use
it for other purposes).
