1 o Code simplification and refactoring
2 - Remove the old 'fuzzy time' logic. It was supposed to be used
3 for handling calculations where we have a known amount of clock
4 skew and an allowed amount of unknown skew. But we only used it
5 in three places, and we never adjusted the known/unknown skew
6 values. This is still something we might want to do someday,
7 but if we do, we'll want to do it differently.
