Aside: I love these 'Time' discussions on HN. Invariably, there is a thread from someone new to the mess that is 'time' that discovers things like leap-seconds or Japanese Imperial Years and is just blown away at the insanity of it all. Then there are discussions on how to implement the logic, with much cursing at Excel. And then someone mentions relativity and everyone just sighs and acknowledges that old Paul Krugman paper. I used to work in an atomic clock company, so all the issues with 'time' are a bit old hat for me. But it's always a blast (honestly!) to see new people's heads explode in these comments as they slowly realize that 'time' isn't really a thing thing. Like watching chicks hatch.
