How come the world can't use GMT for everything every day?

Question

Seems like it would be easier if the time was the same every place in the world..No time zones.

Answer 1

I agree, time is just another way to measure the amount of light and dark. It really does not matter what time we wake up, go to lunch, or sleep. As long as lunch is being served at the sun's zenith, it really doesn't matter what the numbers read. lol

Answer 2

The point being conventional wisdom put the midday at noon and from then on it stuck. Plus it gives a common basis for life: I always get up before 7 AM has the same meaning around the world...

Really if you get used to it GMT is pretty convenient to coordinate different time zones (especially when daylight savings time comes into play).

Answer 3

There is still the lingering notion that we want our clocks to coorespond roughly to solar time. We still want high noon to be noon, for example. We switched over to standardised time zones in order to be consistant with nearby cities, but the desire of a clock being consistent with the astromonical phenomena is still engrained in the collective consciousness.

I doubt that we'll change over entirely to Zulu time except in certain circumstances, such as navel usage and perhaps computer information systems. However, it we develop orbiting colonies, a choice of standardised time would likely be made, and GMT would be a reasonable choice.

Answer 4

Yes it would be a lot easier to use. I use it all the time(no pun)
because I am a pilot.
It would cause mass confusion among the masses as your whole lifestyle would re arrange itself.
Your mind would have a hard time to adjust as your whole life has been from 8-5. It would then be 1-9 depending on where you live.
Simpler yes, easier, no

Answer 5

Do you really think it would be easier to remember that if you both want to go to school during daylight, your friend in Russia would start about 8am and you would start at midnight? And in Japan another time? I think time zones are easier so it is about 6am when the sun comes up.

Answer 6

It has to do a lot with Day light. if i say its 1330 in london and 1330 in Delhi.

how would u know wether its day or night or evening or morning.

with todays system wen i say 1330 IST it menas its 0130 pm in the afternoon i India.

if we folow GMT it will be hell of alot of confusion.

so what we have is fabulous.

Answer 7

Because Earth rotates on its axis and orbits around the sun. The sun remains stationary in space. Therefore, the sun shines on one side of the planet and not the other. The world is round, not flat.

Answer 8

While you're at it...why doesn't the U.S. catch up with the rest of the world and play football with their feet (soccer), instead of with their hands? Why don't they score "under" the goal, instead of "over" it? Why don't they use Kilometers, instead of miles? Why don't they use Kilograms, instead of pounds? Kiloliter, instead of gallons?
How about we all follow Japan, or England, and drive on the left side of the road?
Or do like Australia, and have our water in the toilet flush counterclockwise, instead of clockwise?

Answer 9

That doesn't make sense. Most people stay put in a time zone, so you don't want to annoy the majority to please the minority, who do a lot of travelling or international business transactions.

Answer 10

Because I want to use JTMT, that sets 7AM as the time that I wake up in the morning.
