I'd be interested to hear how you're going to bring it into alignment with GMT and the other Sun-and-Earth-based measuring systems which people are actually going to want to use. Note that the solar day does vary unpredictably in length (https://en.wikipedia.org/wiki/Day_length_fluctuations https://en.wikipedia.org/wiki/Day_length_fluctuations).
- penteract 5y agoHow hard is it to affect the Earth's rotation? It looks like it you would need to change the Earth's rotational energy by ~1.4*10^22 J to change the length of a mean solar day by 1/365 seconds (which would cause UTC to change by 1 second per year). If energy costs 1 cent per kilowatt hour, this is only around $40 trillion, which is much less than I was expecting. If energy becomes a few orders of magnitude cheaper and someone knows a reasonable mechanism to put that energy into the earth's rotation, Google or someone similar might find it easier to keep days at 86400 seconds than to deal with leap seconds.
