Doing a fair bit of time travelling in my fiction, and I avoid all of the nasty paradoxes (paradi?) with the simple assumption that travelling backward in time is possible, but by doing so one ends up in a separate time line. You never alter your past, but you can alter the past of someone who thinks they are you (although this becomes a precondition of their timeline, and is therefore not an alteration.)

Seems like FATE to me.
This is similar to the "all-events-in-time-happen-simultaneously" scenario because all of these parallel worlds must co-exist. To visualize this, imagine time as an X-Y plane instead of a linear line. The progression of time would follow the X axis while every variance of that time occupies the span along the Y axis. So, one could perceive the outcome of some choice by finding that choice on the X axis and looking at various positions along the Y axis to see the result. This requires all parallel realities to transpire simultaneously. If all these realities act in such a fashion, then each reality must be following one of the conceivable threads (because the perception of choice follows a different thread). Therefore, FATE.
