The black helicopters will arrive overhead 3 microseconds later. Relax.
If the day is shorter by 3 microseconds, that would translate into a milisecond per year. That may not sound like much, but for some applications it could become significant. For example, unless GPS satelites are recalibrated (which I would expect should happen), the change in rotation would cause logitude readings to vary by half a meter per year at the equator.
Yes it looks like it is minor but I am going to keep my eye on it. There was a time(about 7years ago) when I was into prophecy. I fell for most of the doomsday senarios about the year 2000 until I was closer to it. I am happy to be wrong about all of that nonsense but something big was suppose to happen in 04 and I was concerned about the earthquake. Just a few days left, I think we will be O.K..
