Or, indeed, the one international border where stepping one foot over the mountains means you step three and a half hours back in time?
Time zones have brought strange quirks to the world ever since 26 countries – including the then independent kingdom of Hawaii – gathered in Washington D.C. in 1884 for the Meridian Conference. In the 1940s, Hitler’s sweep through Europe stopped France using GMT, and put an end to ‘Amsterdam time’, which had the Netherlands running twenty minutes ahead of London. At one point, a tiny Pacific archipelago gave the US the ultimate cold shoulder by literally moving to a different day to get away from them.
And even though it’s probably better than the alternative system, where once upon a time every town set its clock to noon when the sun was at its highest and integration be damned, the standardisation of time zones has resulted in some very strange side-effects.

China’s one-time state
The third largest country in the world, China sprawls across the Asian continent, spanning a sixth of the world’s breadth from the 75 degrees to almost 135 degrees west, by longitude. When the sun rises on the longest day in the far eastern city of Jiamusi, it’s 7:24pm in the UK, but when it rises in the far west, in Kashgar, it’s 11:29pm.
And yet the entire country only has one time zone. I mean, I get it, you want a totalitarian state and all that, but having one part of the country where a winter’s day doesn’t start until nearly 10am seems a little illogical.
In fact, it’s so illogical that half of the city of Urumqi, in eastern China, uses its own unofficial time zone, while the other runs a working day from 11pm-7pm to account for out of kilter day inflicted by Beijing. Which is incredibly complicated – as Apple learnt when a iOS update silently put all users onto the local unofficial time zone, meaning many people’s alarms went off two hours later than they were expecting.
Pleasingly, though, the uniform time zone means that if you can negotiate the Tibetan Plateau and the Himalayas, you can cross over into Afghanistan and set your clock back three and a half hours – the biggest land border time-zone change on the planet. More on that later.
But in conclusion, sort it out, China.

Greenland is another fairly big place (though its position in the far north of most map projections makes it look bigger than it really is). It’s not made the same mistakes as China.
If anything, in fact, goes rather too far the other way. Almost all of Greenland runs on GMT-3, putting it four hours behind its parent nation, Denmark; but a few tiny corners insist on having things their own way.
The Thule Air Base, run by the United States Air Force in the northwest of Greenland, runs on GMT-4, while the Danmarkshavn weather station (permanent population: eight) runs on GMT. For no particularly good reason.
Meanwhile, Greenland’s 18th-largest city of Ittoqqortoormiit (yes, really), runs on GMT-1 along with pretty much nobody except the Azores and Cape Verde.
Not actually Newfoundland but the annoying French thing. Image: Ken Eckert.
Staying in a similar geographic locale, the Newfoundlanders decided to screw up the orderliness of Canada’s time zones. The bulk of the country makes things simple enough, running from GMT-4 in the east, through GMT-5 in Toronto and Québec, GMT-6 in Winnipeg, GMT-7 in Edmonton to GMT-8 in Vancouver in the west.
Newfoundland, though? “Nah,” they thought. “Let’s go with GMT-3.5, because we’re cool.”
That’s basically because Newfoundland was a separate colony when time zones became a thing, so it had the right to establish its own time zone. About a hundred years later in 1963, when it had been subsumed into the independent nation of Canada, the provincial government tried to click it back into sync with the rest of the Atlantic region of Canada. The move was basically thwarted by a bunch of time NIMBYs. The state of you, Newfoundland.
Though in fairness the 6,080 people of St Pierre and Miquelon, a hang-on dribble of islands from the days of the French Empire, stubbornly sticks to GMT-3 even though the nearest functioning place that uses it is… Brazil.

The half-hour gang
Which brings us to the main cluster of countries where somebody decided it was vaguely acceptable to sit half an hour out of kilter with the rest of the world.
Iran runs on GMT+3½, Afghanistan on GMT+4 ½, India is on GMT+5 ½, and Burma uses GMT+6 ½.
The reasons for all of these aren’t entirely clear, although given the heavy involvement of the British Empire and its tendrils in the region, it’s highly likely that it’s all our fault.
Indeed, India’s standardised time zone, though half an hour short of being sane, isn’t as mad as it used to be before it became independent. During the Raj, the colony operated three main times: Bombay Time, at GMT+4:51 (yes); Madras Time, at GMT+5:21 (I know); and Calcutta Time, at GMT+5:54 (I’m not even making this up).
As for Afghanistan, if in doubt just blame Tony Blair and hope everybody stops asking questions.
Oh, and then there’s North Korea, which runs on GMT+8½, but that doesn’t particularly matter because nobody likes them anyway.
Good fields, though. Image: United States Department of Agriculture.
The Ne-pallingly confusing time zone
Perhaps the most screwed up entire nation in time terms is Nepal, which runs GMT+5¾. In theory, it’s because mean time in Kathmandu – aka, the approximation across the year of when the sun is at its highest at noon – is 5 hours, 41 minutes and 16 seconds ahead of GMT.
Still ridiculous, though.

Too close for comfort
Obviously, eventually you get so far round the world that the whole thing starts all over again. If you don’t know what I’m talking about, sit on the edge of your seat through any adaptation of Around The World In 80 Days and be amazed.
In essence, the International Date Line is the exact opposite side of the world to the Greenwich Prime Meridian, and is where you stop being ahead of London and start being behind it. In other words, in the far east of Russia they’re already starting tomorrow, but Alaska’s only just got going on today.
The problem is that although the Pacific Ocean is a handly empty place to dump a line where there are two days, it’s not totally empty, so the line strays a little.
The very far eastern island of Big Diomede in Russia runs on GMT+12, even though it’s just 2.4 miles away from the closest part of the USA at Diomede, Alaska, which uses GMT-9. The Aleutian Islands – basically, Alaska’s tail – stretch across the 180-degrees line that is the theoretical International Date Line, but all use GMT-10, because it’s just easier.
But there are two places where the line has shifted in recent history, giving rise to some strange goings-on.
In December 2011, Samoa jumped forward a day, and just missed out 30 December (nobody got their six geese a-laying that year). This was to get rid of an old hangover given to the country by its king in 1892, who moved the country east of the Date Line to bring it closer to America. This became impractical as Samoa grew closer to Australia and New Zealand, its much closer neighbours, and so the 2011 moved the country from being 21 hours behind Sydney – the nearest major business hub – to being three hours ahead of it, which made more sense.
Though, sadly for the Americans, it left American Samoa marooned, only 70km away but 24 hours apart (25 in summer).
And then there’s the Republic of Kiribati, which became independent in 1979 by combining three colonies – the UK’s Gilbert Islands, and the Phoenix and Line Islands from the US. But this was a problem, as the former ran on GMT+12, while the Phoenix and Line Islands ran on GMT-11 and GMT-10 respectively.
So they shoved the whole country over to the western side of the Date Line in 1995, creating the time zones GMT+13 and GMT+14, and dragging the whole line 2,000 miles eastward. When you remember that the Line Islands are further east than Hawaii and most of Alaska, this is pretty weird.
Most fun quirk of all of this means that for a brief moment every day (sort of) there are three days going on at once (wibbly-wobbly, timey-wimey… you know the drill). At 10:30am on Wednesday in London, it’s 11:30pm on Tuesday in the inhabited New Zealand-owned island of Niue, and 12:30am on Thursday in the Line Islands of the Republic of Kiribati (pronounced “Kiribas”).
What a mess.

In theory, this isn’t difficult. You take your big country, helpfully divided into states running east to west, and you give them relevant time zones.
The state of Western Australia runs on GMT+8, which is fine. Job done. The states of New South Wales, Tasmania, Victoria, the Capital Territory, and Queensland run on GMT+10. Which is sort of fine.
The logical thing for the middle states of South Australia and the Northern Territory to do would be to run on GMT+9, right? Especially as they almost perfectly straddle 135 degrees west, the centre of the +9 time zone area.
But no. They run GMT+9½, because there is nothing pure left in the world.
And even that’s not enough by way of complication. The southern states of South Australia, New South Wales, Tasmania, Victoria, and the Capital Territory use daylight saving time, but the other three states don’t.
So for half the year, Australia goes from having three time zones to having five. What a mess.
To make it worse, there’s Lord Howe Island, which is technically part of New South Wales, but is off halfway to New Zealand. During the southern hemisphere winter, it uses GMT+10½, just half an hour ahead of Sydney and the like, but in winter it uses a daylight saving time half an hour ahead – running at GMT+11. Which makes it the only place in the world that does not switch a full hour for daylight saving time.

Specifically these Australians
Because some people just want to watch the world burn, there’s a tiny town of 86 people in the far east of Western Australia that decided to be quirky and just invent its own time zone.
Eucla, and a few poor stragglers nearby, uses GMT+8¾. Apparently with this time nonsense you can basically just do what you want.
Nobody tell Cornwall, they’ll get ideas.
Hey guys, remember that time Russia had daylight saving time in the summer and then just stayed there because they liked having light evenings? So relateable. Except then loads of people had car crashes in the morning so they switched it back.
