Er, what? If I look at the clock and see it’s 0955 I know exactly that it’s 35 minutes. Same for every other example you give. If it’s 1252, it’s so easy to add 8 minutes then add whatever it is more. And you can do that for any time. Say 1017. “Oh no!” Never fear, the just add it to the time wangs are here: +13 to 30 and woah! Easy, foolproof and actually intuitive
1030-955=75. So intuitively, it would be 75 minutes until the meeting. Oh wait… maybe it’s not intuitive?
210 degree arc is always going to be 35 minutes. Whether it’s the 35 minutes from 9:55 to 10:30 or 9:50 to 10:25 or 3:15 to 3:50 or whatever. Sure you have to get used to the arcs. But once you do, it’s a quick glance at the minute hand and seeing how far away it is from the time of the meeting (or whatever the next thing is). Time for a computer is a number, time for a human is how long until a thing is going to happen.
