I have a modest proposal to end all time-zones forever: the fractalizing time grid.
Currently, partly due to a historical legacy of railroads, time-zones are longitudinal. That is, they help standardize time (and daylight hours) across east-west distances.
However, given that the number of daylight hours is even more starkly affected by north-south latitudinal differences, we should also implement time-zones in that direction. After all, what does "12:15am" really mean if its dark in London and sunny in Reykjavik?
So, in order to standardize daylight hours, we could implement north-south time-zones as well, producing time-offsets for each lat/long cell on the globe. We could standardize the number of daylight hours in a given 24-hour period (using the equator as reference) and standardize each cell to have the same number of daylight hours.
In order to do so, we would simply have to redefine what a "second" is (or really, all time measurements.) So, the further north you go during the summer, the shorter a "second" becomes (so as to preserve the same number of "seconds" per time-cell) whereas in the winter you would have the opposite effect. Therefore this also has the interesting consequence of changing the duration of all time measurements seasonally, with a greater delta the further away from the equator you are (a "second" would always have the same duration at the equator.) So the further away you are from the equator, the quicker the duration of time changes with respect to equatorial time as time passes seasonally. Still with me?
Good, because we can do even better! Why even have time cells? Time-zones were implemented as lines on a map because that was the technology that was available at the time. But now that we have the internet, we can instead standardize an algorithm that could be implemented into all RTC chips and run on reference servers a la atomic clocks. So instead of "crossing over" into the next time cell, all of your time measurements would be sped-up or slowed-down proportionally to your GPS-measured latitude (standardized to some number of significant digits.)
So all analog clocks would immediately be rendered useless -- unless you are exactly on the equator -- and we would live in a world where you could speed up time by running north, but only in the summer.
If you've made it this far without throwing your laptop/phone out of the nearest window in rage, thank you for your patience (and welcome to the time grid!)
