Nantucket and The Time Patrol
a Time Patrol vehicle disappears from one set of spatiotemporal coordinates and appears at another without existing at every intervening space-time point;
Nantucket traveled in this way;
Wells' Time Traveler on his Time Machine and Anderson's Jack Havig exercising his psychic power do exist in the same position on the Earth's surface at every moment between departure and arrival;
the anakro in Anderson's The Dancer From Atlantis follows a great circle on the Earth's surface while moving backward in time;
Anderson's Wardens and Rangers walk or drive along their time corridors;
spaceships flying around T-machines make long interstellar space journeys as well as time journeys;
both the time projector in Anderson's "Flight to Forever" and Doctor Who's TARDIS exist in something like hperspace (or hypertime?) between departure and arrival;
in fact, the Doctor refers to "the Time Vortex."
So how many kinds of time travel are there?
