Batman had that happen to him once in one of the cartoons. Some clock theme guy put him in a slow time field in the middle of the highway... it took him 3 days to the outside to counter it in 5 minutes. Basically, Force still equals Mass times Acceleration... and it equals that for each time interval (lets say a hundredth of a second). so once the time fields synchonize F=(MA)^T instantaniously for that moment of sync... Which probably means which means either giant explosive release of energy... or in the case of how it was handled in one of Undocumented Features stories, where a static timefield was put on a door and constant force was applied to it until right before the field shut off, the door was hit with the culmulative force used up to that point on it. Meaning the door caved in badly.
Edit: This is why I think that what the Flux Capaciter does that makes the Time Traveling object slightly out of phase with the dimension your time traveling in. Thus the reason that Time Travel experiments tend to lead to explosions is that the time traveling object is hitting air molecules and the like and the energy involved in Time Travel is exceeded by the build up of F=(MA)^T feedback... meaning BOOM!!!.
I heard that photons have been shown making short trips back in time... this is probablly possible (speculatory science in progress) only because they are so small that they not only hit less random stuff... but being smaller than an electron any actual explosion is very small and involving ultra small amounts of matter so ultra small we can't even see the particals exploding in the first place... the explosion itself may actually be what stops them from going back in time father than a few seconds/fragments of a second.
