Sure, there are a handful of places which use a time zone with a 30 minutes offset.

And an even smaller number of places with a 45-minute offset. See Nepal Standard Time.

How often do you need to know exactly what the time is in another part of the world?

I attend at least three or four online meetings with colleagues based in the US, Germany, India, Chine and the Philippines. I have an idea of what the time is there, but could easily be out by an hour or two, but it doesnít matter - my calendar reminds me fifteen minutes before the meeting. I then go and make a cup of tea or coffee, and connect.

Even if youíre pedantic enough to need to know, half hours arenít rocket science.

I need to know when I can call my mother in Oz, and consult the online World Clock. The time difference can change.

If you go to India from the UK (or, more accurately, somewhere with UTC) turn your (analogue) watch upside down and the hands will point to the correct time. Interesting quirk of being 5.5 hours ahead.

Doesn't quite work, unfortunately. If it's noon UTC and you turn your watch upside-down, then both hands will point towards the 6. The minute hand will be in the right position, but the hour hand will be half an hour out. The display could be taken to indicate 6.30 just as easily as 5.30.

All things considered it's a pretty good lifehack though, right?

I think it'd be less confusing to simply change the time on your watch!

The hour hand will always be half an hour out, no matter what time it is.

I frequently have meeting between here, Hyderabad, Manila, and Tokyo. Whichever time of year and however you juggle it, with that set-up one location will always be fucked.

Tom Scott: The Problem with Time & Timezones

Time zones and computer programming problems: He mentions Australia as 9.5 hours ahead of GMT. Must be South Australia, which is where Brady Haran is from, so that makes sense, because this is from Computerphile, one of Brady's channels.

Be glad you're not living in the West bank, if you think time zones are hard to deal with :/

Is it a better or worse idea than the Romans dividing up the day with 12 hours of daylight and 12 hours of night?

Ahem, Egyptians originated this - by picking out the rising/setting of 12 stars at night and then replicating the idea for daytime.

I did not know that, thanks. I'll have to read about it.

The Japanese also did this. There's a great exhibit in the Japanese room of the British Museum of an early Japanese clock. Clocks were invented in Europe and exported to Japan when trade between the two was established.

The British Museum exhibit explains that early Japanese clocks had to include a complicated mechanism to vary the length of the hours so that each day and night were divided into 12 hours, no matter what the time of year.
