What’s interesting is that the Earth is undergoing an odd span of time during which it has been spinning a bit faster instead of slowing down. If this keeps up, not only will it be a while until we see another leap second, but in a few years we might experience the first negative leap second, where a second is dropped from the end of the last minute just before 00:00 UTC.
