Asia has the most time zones, ranging from UTC+02:00 in Turkey (two hours ahead of UTC or GMT) to UTC+12:00 in the easternmost part of Russia. That's 11 primary time zones.
In addition, Asia has four time zones that are half an hour off from the rest of the world:
All in all, Asia has 15 different time zones.
Europe has only 4, Australia has 4 (including a small rural area that is UTC+08:45), Africa has 4, South America has 4 (including UTC-04:30 in Venezuela).
North America has 9 (if you include UTC-03:30 in part of Newfoundland, UTC-03:00 on the islands of St. Pierre and Miquelon, and UTC-10:00 in Hawaii and the Aleutian Islands in Alaska). If you include Greenland as part of North America, then North America stretches across 11 primary time zones, from UTC+00:00 to UTC-10:00, but no part of North America actually observes UTC-02:00 as its standard time zone.
(There are no time zones in Antarctica.)
Asia and Antarctica are the only continents that have nonstandard time zones. In the 1920's other areas of the world changed to standard time zones to avoid railroad trains from colliding into each other.

I'm not sure what you mean by "non-standard time zone". Assuming you are referring to a time zone whose offset from UTC is not a multiple of a whole hour, North America has Newfoundland Standard Time/ Newfoundland Daylight Saving Time (UTC-3½/UTC-2½), and South America has Venezuela Time (UTC-4½). However, Asia and Australia top the list with five each (if you include Australia's island territories).
Asia has...
Australia has...
The only other time zones in the world that are similarly non-standard are Marquesas Time on the Marqueses Islands of French Polynesia (UTC-9½) and Chatham Islands Standard Time/ Chatham Islands Daylight Saving Time (UTC+12:45/UTC+13:45).
If by non-standard you mean zones whose offsets from Coordinated Universal Time (UTC) are not multiples of a whole hour, they are, in alphabetical order...
Bolivia, Guyana, Bermuda, Chile, Paraguay, the Falkland Islands, most of the Caribbean islands (all except Cuba, Jamaica and the Haitian half of Hispaniola) and parts of Brazil, Canada and Greenland have a standard time offset of UTC-4. Cuba and parts of Brazil, the United States and Canada have a Daylight Saving Time/ Summer Time offset of UTC-4.
India Greece Australia I do not know the fourth
Every bit of inhabited land on Earth is now part of a standard time zone.
Every continent has time zones, but Antarctica is the only one that is not COMPLETELY divided into time zones.
Australia and Asia! :)
The continent is Antarctica.
Yes, every country in the whole world uses time zones. But some countries are in only one time zone, like Greece
Yes, there is such a country.China spans five time zones. However the Chinese have "joined" their five time zones together and use just one nationally. Which means some parts of the country don't get to see the sun rise until 10am in Chinese national time.Yes, countries that used to have multiple time zones but now have only one are...ArgentinaChinaMalaysiaMarshall Islands
Time zones simply create a workable 'day' and 'night'. If countries didn't use time zones (and the whole planet worked on the same time), people would be going to bed at (for example) 9am just because it was dark then. Time zones bring sensibility to daily life. The only disadvantage - is having to adjust to different times when you travel overseas. For example - it might be 8am when you depart, but (after travelling through a number of time zones) - it might only be 2am local time.
Meridian lines can be used to measure time zones. They split Earth into different time zones.
One would think the answer is 24. But no. There are a total of 55 about time zones in the world. Why so many? Each country decides their specific time. Most will adhere to a regional time zone, bit many will countries and regions that have their own time zones that are off by 30 minutes from the time zone around them such as Newfoundland, Venezuela, India, and Iran. Some are off by 15 minutes such as Nepal. In the Pacific several islands have their own time zones. They will share the same time as a neighboring island, but they are one calendar day ahead or behind their neighbors.

we were using the nonstandard set of measurements

It is a huge country. The U.S. has 4 time zones.

You can invent any number of nonstandard units, but none of them is "best". It is best to use standard units, that is, the meter.
The Chass Port of Call clock is a popular attractive design which allows the setting of multiple time zones for display at the same time.
western time. i need eastern time
There is no law that all time zones have to have a whole number of hours offset from UTC. Most countries do use whole numbers, though.
They wanted large buffer zones to use in time of war to prevent invaders from actually reaching their home territory.
