Hi Frank
The word "amazingly" was used in a tongue in cheek manner. Nothing amazing about 15 degrees multiplied by 24 (time zones) getting 360 degrees, or one revolution.
---------------------------------------------------------------------
Nothing amazing about 23 times 15 plus 2 times 7.5 getting 360 degrees either.

Mr. La Pook
Sure, the description of time zones is in every text you have read. Everyone agrees on this, by definition. The Navy wanted this definition in its texts for obvious reasons. Your opinion that it is 'wrong' doesn't make it wrong. It just places you in a somewhat logically precarious position. Gary versus the world, or something to that effect.

At one time everyone thought that the earth was the center of the universe and that all the celestial bodies went around the earth. They were wrong too. So I'm not worried by being the only one pointing out when a majority is wrong.

Brad, you wrote:
"Amazingly, it shows 24 time zones."It's just a question of terminology. You can certainly legitimately say that there are 24 nautical time zones. The time changes by one hour as you go from one to the next at precisely defined boundaries of longitude. But there are 25 nautical zone descriptors. This happens because the zone straddling 180° longitude is split into two zone descriptors by the nautical dateline. If we make an identification of time zones to zone descriptors, then there are 25 time zones because there are 25 zone descriptors. But if the nautical time zones are kept as a distinct concept, then there are 24 time zones --but still 25 zone descriptors.-FER
