OK, let's put on our thinking caps. How many standard time zones are in the world?

This question came up at lunch the other day. When asked, I immediately said there are 24 time zones, related to the time it took the Earth to complete one rotation.

Then, an executive (with a Master's degree) barked that there were more like 12 time zones and the rest of the people in our discussion agreed with him.

Now, discounting idiosyncrasies like some zones having Daylight Savings Time, and other quirks, doesn't the world basically operate under 24 standard time zones? Or, am I missing something?

Plus or minus where you're starting from.

Get a globe out and look at the time zone lines.

is the opportunity to kiss ass like the rest of your group did. He may learn he is wrong, but you will never get credit for being right. Sounds like a GE company.

Standard time zones can be defined by geometrically subdividing the Earth's spheroid into 24 lunes (wedge-shaped sections), bordered by meridians each 15° of longitude apart. The local time in neighbouring zones would differ by one hour. However, political and geographical practicalities can result in irregularly-shaped zones that follow political boundaries or that change their time seasonally (as with daylight saving time), as well as being subject to occasional redefinition as political conditions change.

Your pal must be on drugs, Master's degree or not. It certainly wasn't a Masters in Astronomy.

:evilgrin:

We have similar disputes here in Canada, including a "1/2 hour" time zone (Newfoundland).

there's 42 beers in a metric 6 pack.

:silly:

You know, George Bush has a Master's degree, from Harvard, no less!

:rofl:

There are many at UTC +/- X.5 hrs, etc.

I will let you count them.

:D :shrug: :silly:

There is simply no other reason to pass all those boring classes, and you better not forget it.

What's the meaning of "standard"? There are 24 time zones, and, within some of them, there is Daylight Savings Time and Standard Time, depending on the date.

Sounds to me like your Master's degree guy - just remember that attaining a degree doesn't necessarily mean you learned anything - has his head up his ass.

Ask him to explain the International Date Line and watch his head explode.

Then, with half the world to cover, what do you do? You just jump or go back 12 hours?

How does that work?

Makes sense to me (LOL)

Hugo Chavez set Venezuela 30 minutes behind... oops I mean 30 minutes ahead of... the rest of us.

As soon as you said it, most people would have realized he was full of it.

Hope this is a temp job.;)

We were at lunch and the restaurant had several clocks indicating the time somewhere else. All of the clocks had a different minute setting. Another person from work said something that compelled me to explain the clocks were obviously wrong time zones were in even hour increments. In other words, it would not be a quarter past the hour in one location and half past the hour in another.

I was told by the other guy that was wrong. He said that while he was in the Navy there were several instances where a "formula" had to be applied to determine the correct time settings. Or some such.

Now I did notice someone mentioned 1/2 hours above (and I had not realized that). Can someone clue me in if there are instances where the time difference is not in even hour(s)?

Thank you in advance!!

Obviously, not each time zone is going to be exactly 60 minutes different. There are seconds' difference, but not enough to make any kind of significant difference unless you're, you know, firing missiles at Iran or something like that.

There are more than the 24 zones you conceive of, because Kiribati wanted to be the first country to greet the year 2000. From memory, there are countries 12 hours behind GMT and countries up to 14 hours ahead of GMT. That makes 26 timezones even by your definition.

There are countries with 30-minute offsets from the 24 timezones you mention.

There are even countries with 15-minute offsets.

Oh, and there's Saudi Arabia, which uses (or has used) solar time (which tracks a sundial and varies plus or minus 15 minutes from a standard timezone).

And when you take into account the dates at which countries, or parts of countries, switch to or from daylight savings time (which is known, in more sensible countries, as "summer time" because you aren't actually saving any daylight) then Indiana alone counts for a fuck of a lot of timezones.

More details here.

And here are the timezones my computer knows of. Some of them keep the same time exactly, all year around, but are kept distinct because they are in different countries and politicians can (and frequently do) tinker with timezones. Others, like the many Indiana timezones, differ (or have differed at some point since 1970) on the dates at which they switch to/from daylight savings (or whether they observe it at all).
