| > It is irrelevant until it is not: just ask Julius Caesar and Pope Gregory XIII. You're refferring to needing to reform the entire calendar but this doesn't make sense in context of me explaining that the calendar itself never needs to be reformed in the first place. That the sun was a few degrees different in the sky for Julius Caesar when a modern clock reads 3 PM in his time is not inherently a problem as Julius Caesar wouldn't have the same norms as you do in terms of what wall time is acceptable for waking/sleeping/eating/working/etc. E.g. 20,000 years from now if a clock reads 3 AM during midday it' not a problem as society will have had 20,000 years to adjust 12 hours vs your referenced calendar reforms that changed everything overnight. > The difference of an hour does make a difference, as sleep researchers and chronobiologists keep pointing out every time a discussion on DST comes up (it is not just about the sudden time jump, but also about the actual time): Again, you're missing the forest through the trees - though in two different ways here. The first is that it's a minute over someone's (long) life, so what impact we feel when we change time by an hour twice a year isn't relevant. The second is that society, over 2,000 years, does not need to change timekeeping itself to wake up when the clock says 8 instead of 7. If the change were to happen over a short period then sure, it's not really feasible for society to move up what wall time their breakfast is four times a year or something, but an hour a millenia isn't even something society needs to consciously worry about. My point is not that we don't have a biological clock, it's that the effect of leap seconds on a human's biological clock are too small to affect it. One of your sources already says it's 15-20 minutes misaligned a day, why are you using it to argue 1 additional minute for your entire life is impactful? On the long term societal scale my point is society won't always agree we should wake up when the wall clock says 7 am. That norm changing shifting ~an hour 2,000 years is not a relevant concern for changing the way we keep time. |
