The creator of DST gets the first slap. Then the timezones asshole.
I’m planning to do a presentation at work on how to deal with dates/times/timezones/conversion/etc in the next few weeks some time. I figure it would be a good topic to cover. I’m going to start my talk by saying “first, imagine there is no such thing as timezones or DST.” And then build on that.
Sandford Fleming (the guy who invented time zones) actually made it easier.
Before timezones, every town had their own clock that defined the time for their town and was loosely set such that “noon is when the sun is at its highest point in the sky.” Which couldn’t be measured all that accurately.
If it wasn’t for Fleming, we’d be dealing with every city or town having a separate time zone.
Save a slap for the dude who invented sundials, and another slap for the dude who invented civilization.
Some asshole had the idea to water a seed and now I have to pay taxes. Fuck that guy.
Imagine, if we were just all on the same time. It’d just make things, a little easier.
All in the same time? But… Then the sun might go down at noon. That doesn’t make sense…
Wait… Noon? Noooon…
The word noon comes from a Latin root, nona hora, or “ninth hour.” In medieval times, noon fell at three PM, nine hours after a monk’s traditional rising hour of six o’clock in the morning. Over time, as noon came to be synonymous in English with midday, its timing changed to twelve PM.
Oh now that’s worse

Oh yeah, please do imagine there is no such thing as a time zone.
On an ellipsoid!
No, see, how it would work without timezones is:
- Everyone would use UTC and a 24-hour clock rather than AM/PM.
- If that means you eat breakfast at 1400 hours and go to bed around 400 hours and that the sun is directly overhead at 1700 hours (or something more random like 1737), fine. (Better than fine, actually!)
- Every area keeps track of what time of day daily events (like meals, when school starts or lets out, etc) happen. Though I think generally rounding to the nearest whole hour or, maybe in some cases, half hour makes the most sense. (And it’s not even like everyone in the same area keeps the same schedule as it is now.)
- You still call the period before when the sun is directly overhead “morning” and the period after “afternoon” and similarly with “evening”, “night”, “dawn”, “noon”, “midnight” etc.
- One caveat is that with this approach, the day-of-the-month change (when we switch from the 29th of the month to the 30th, for instance) happens at different times of the day (like, in the above example it would be close to 1900 hours) for different people. Oh well. People will get used to it. But I think it still makes the most sense to decide that the days of the week (“Monday”, “Tuesday”, etc) last from whatever time “midnight” is locally to the following midnight, again probably rounding to the nearest whole hour. (Now, you might be thinking "yeah, but that’s just timezones again. But consider those timezones. The way you’d figure out what day of the week it was would involve taking the longitude and rounding. Much simpler than having to keep a whole-ass database of all the data about all the different timezones. And it would only come into play when having to decide when the day of the week changes over.)
- Though, one more caveat. If you do that, then there has to be a longitudinal line where it’s always a different day of the week on one side than it is just on the other side. But that’s already the case today, so not really a drawback relative to what we have today.
You still call the period before when the sun is directly overhead “morning” and the period after “afternoon” and similarly with “evening”, “night”, “dawn”, “noon”, “midnight” etc.
Note that the Sun position is not consistent throught the year and varies widely based on your latitude.
In Iceland (and also Alaska) you can have the Sun for a full 24 hours in the sky (they call it “midnight sun”) during Summer solstice (with extremelly short nights the whole summer) and the opposite happens in Winter, with long periods of night time.
I think it still makes the most sense to decide that the days of the week (“Monday”, “Tuesday”, etc) last from whatever time “midnight” is locally to the following midnight, again probably rounding to the nearest whole hour.
Just the days of the week? you mean that 2024-06-30 23:59 and 2024-07-01 00:01 can both be the same weekday and at the same time be different days? Would the definition of “day” be different based on whether you are talking about “day of the week” vs “universal day”?
regarding day change, you could also just have it change at UTC midnight and the entire planet bongs at that time if they’re awake.
