you realize we wouldn't have 24 hour days in that case, right? we would lose almost 4 minutes from each day with that standard.Standard time year round. Noon in the middle of the daylight part of the day; the logical basis of all timekeeping.

Ok. I am with you. Here's where I am lost:One Earth rotation takes 23 hours, 56 minute, and 4 seconds.
Ok. I am with you. Here's where I am lost:
We use a 24 hour clock. That clock is "off" by 3 min 56 seconds each day. And it is "off" whether we are on standard time or on dst.
why would assigning the high point of the sun every day as 12:00 noon be different?
Neither Standard time nor DST would keep the sun at high noon except for maybe 1 day, but I doubt it. that is the reason we have other adjustments, to correct for that time difference.Ok. I am with you. Here's where I am lost:

LOL. I was actually thinking that same thing.That’s a question for Neil deGrasse Tyson. It makes my head hurt. But the 3 minute 56 second shortage is why we have leap years.
I am sorry. I still don't understand.Neither Standard time nor DST would keep the sun at high noon except for maybe 1 day, but I doubt it. that is the reason we have other adjustments, to correct for that time difference.
either we would need to adjust the relative time of "noon" each day while keeping a 24hr day, accept the 23hr 56min and 4 second "day" and adjust our hours accordingly, or we end up with leap days/years and the sun pretty much never directly overhead at 12 noon which is the current solution.
There are multiple levels to the adjustments. not every 4 years do we get a leap day, according to wiki its every 100 years we DON'T add a leap day. but we do every 400 years.LOL. I was actually thinking that same thing.
Here's another head scratcher...we add almost 4 minutes to our rotation. our solution to the daily added minutes is to add a full day once every 4 years. Seems like we should subtract a full day once a year to correct the overage.
