A while back, we were playing an online trivia game at lunch at work one day. We did it in team style, so we were pushing 100%. But when we got the answer wrong, per the game, I would usually be the one arguing why we were right. And after a bit of research, I was usually proven right.
This one question still bugs me. "How many time zones are there?" . The answer the were looking for was "24". Which is blatantly wrong. After a bit of arguing, I started the research. Not even google knows this answer. There are so many conflicting answers, I came up with anywhere between 72 and 115. Found this wonderful little video tonight about how a programmer deals with timezones. Even if you're not a coder, you'll still enjoy it. |

overthinking the issue i would say
traditionally speaking there are 24 time zones, each one consisting of 15 degrees, with each 15 degree interval representing one hour i had this discussion with a friend of mine when we were in Midland, Texas earlier this year. He had noted that it was 7:00 in the morning, yet there was still very little daylight comparable to what he was used to seeing at 7:00 in the morning where he lived in Biloxi, Mississippi despite both areas being located in the central time zone I explained to him that because the earth is spherical and we are located at nearly the westernmost extreme of the central time zone it would be dimmer there, and brighter in Biloxi because the sun is several degrees higher in the sky in Biloxi, Mississippi than it would be in Midland, Texas. I further explained to him that, depending on your location on the earth with respect to latitude, you would actually have to adjust your clock every few miles that you travel east or west and because of this it is actually closer to 6:15 am than 7:00am even though the clocks are all set to 7:00 am not to make my friend sound stupid, because he is actually very intelligent, but this just goes to show that very few people actually think about it really. the whole argument about the time change from standard to daylight savings time is invalid in my opinion, because (1) not all areas participate in the concept (2) the time change concept is a construct of man not nature and (3) time has been proven to vary depending both on gravitational density and speed and our time zone concept corrects for neither a moving clock or the variability of gravity from one place to another on the surface of the earth.

I don't grasp this stuff too well, but you may be interested to know that the Greenwich Meridian line passes through my road just a few hundred yards away.
I once took my nephew (from the US) to see the marker and postulated that if he were to lay his wedding-tackle on the road, across the line, then he could go home and brag about having one so long that it could cross two time-zones.

"...and suddenly you have sixty-one seconds in a minute!"
![]() You could have millions of "Time Zones" if you wanted, because when the center of the sun is directly above your exact line of latitude it's only a second away from not being there. Time Zones were created by the railroads to make it easier to say exactly when a train would be arriving. Arbitrary changes such as Daylight Savings Time change the time within the zone, but the zone itself does not change. Even going from before the IDL to behind it, while it may change the day, does not change the zone itself. Sorry, for all the hilarity in that video, and seeing how whacky some of the lines can be, there are still only 24 time zones.

Any division into zones is arbitrary, and there are as many or as few as people agree to use for a specific purpose. And just to add to the confusion, take a look at this clock on the The Exchange building, Bristol. Two minute hands! (From Wikipedia: https://en.wikipedia.org/wiki/The_Exchange,_Bristol "the red minute hand shows Greenwich Mean Time and the black minute hand shows Bristol time") |
