Time Issues

I know not what I have stumbled upon, but it seems I have found a loophole in the time/space continuum. Scientists may credit the whole idea to the unreliability of the Chicago's elevated train system. But no matter when I leave my house, be it an hour ahead of schedule or a half hour behind, I arrive at work fifteen minutes late. My employer is understanding in this. So, I am not in fear of being penalized, but I am in awe of it and I seem to be stuck in this odd reality each and every time I go to work. Does anyone else have one of these worm holes in their lives? Or am I alone?
