I don't know about time or logic in exact terms. But, I would say that if Vowzra wasn't able to survive in the gap, then at the very least it doesn't work in the same way as the material world.

My theory is that time is made subjective in the gap as physics is no longer present to funnel possibilities into a single present. So, different places in the gap are no longer guaranteed to be in the same point in time and no two places in the gap are guaranteed to have time progress at the same rate. So, time still exists, it just doesn't conform to material constants and understanding (like most things in the gap, really.)
