This has made me wonder which places have a “standard time” that is farthest removed from mean solar.
China, despite covering several hours of longitude, uses a uniform time zone of UTC+8. The Western-most part of the country in the Xinjiang Uygur Autonomous Region is 3.1 hours ahead of solar time. Typical sunrise times in spring and autumn are around 9 am, whereas in winter the sunrise can be as late as 10:15 am. Kind of thing you can get away with when you’re a one-party state with no concern for regional minorities I guess. I think this might be the winner.
Argentina is on UTC-3 which is quite advanced of its geography. The westernmost parts of the country are 1.9 hours ahead of solar.
The westernmost point in Canada’s Northwest Territories is 2.1 hours ahead of solar.
Malaysia in UTC+8 is quite advanced of its solar time, and the westernmost part is about 1.4 ahead.
Iceland for some reason uses UTC+0 (ie GMT) despite being halfway across the Atlantic and its westernmost point is 1.6 hours ahead of solar.
Spain uses UTC+1 and its western parts are 1.6 hours ahead of solar.
The Western Aleutian islands in Alaska, USA, are on UTC-10, which is ahead of solar. The westernmost island would be Attu, 2.5 hours ahead of solar. The main part of Alaska is on UTC-9 but that’s still ahead of solar. Hall island and St Lawrence Islands would appear to be the most out of wack in that zone, also about 2.5 hours ahead of solar.
Algeria’s ahead of solar in its western margin in particular is 1.6 hours ahead of solar.
Russia experimented with shifting its timezones an hour about 10 years ago but went back to normal in 2014. Sudan also had an advanced time but went back to something closer to solar in 2017.
On the whole there is definitely a trend worldwide to be ahead. There are some places that are pretty much in the right zone. Australia (except for SA/NT), Indonesia, Philippines, PNG and NZ kind of. Eastern China basically has the right zone. Can’t complain about Korea or Japan. India, Iran, Brazil, honestly most of Africa and South America can say the same. About half of the states of the USA are currently in a zone that is appropriate for their solar time.
There aren’t many places that are way behind their solar time. Greenland, being near the pole, has a big longitude range and some of its eastern margins are a couple of hours behind solar but those are in uninhabited areas. Apart from that, the easternmost points of India, Turkey, China are about an hour behind but that’s not too bad.
I do wonder why nation’s persist with these astronomical fictions, though. I mean if the USA wants to go an hour ahead … fine, whatever … but effectively all that will happen is that people will be doing everything an hour earlier. People who currently get up at 1500 UTC will now be getting up at 1400 UTC, they’ll be lunching at 1900 UTC instead of 2000 UTC etc. … why not just normalise doing those things an hour earlier than currently so you don’t have to mess with the clocks?
