Or do you think time goes in Cycles? Where each cycle has a starting and ending point, but restarts afterwards? Kind of like temporal rebirth.
Time is neither because it doesn't actually exist (at least not ultimately). What we experience as time is actually something like holographic (really - take a look at the Avatamsaka Sutra for example).
Time in physics is mostly a mathematical abstraction dealing with entropy, so the flow of energy. Time in this sense can also be seen as holographic in a sense according to Kip Thorne (I think it was Thorne) who proposed that in a Big Crunch situation, time would replay itself (so it would appear to be cyclic) but all at once. So it might be experienced as a set of infinite reenactments of the past 16B or so years all in an instant, thus creating eternity in a finite space of time (in the end an infinitely short span of time). I'll have to revisit Thorne's thesis to make sure.
However Heat Death appears to be the case in the physical universe rather than the Big Crunch. So information in this universe will not be replayed in any form* although according to the multiverse people, there many be an infinite set of universes, setting the stage for taking Nietsche seriously when he mused about this universe being infinite and thus spawning infinite Nietsche's and thus a form of eternity. A truly infinite set of finite universes guarantees that a form of time is eventually replayed in an otherwise indistinguishable other universe.
*but wait - time travel to the past is actually possible - you just need a cylinder along the axis of the universe, the length of the universe, rotating at the speed of light and according to Thorne again, you could travel to the past. So it's just a matter of engineering.
