Communication and transportation were so slow that it didn't matter that every city was on a different time.

vegetation zones are zones that are made up of common vegetation characteristics
Time zones were in use decades before 1883. Iceland's started in 1837, and the U.K. started in 1847. 1883 was when the United States adopted them, and as much as this information is going to break your heart, I have to tell you anyway: we are not the center of the universe. Before time was standardized into zones, each city kept its own time. As the railroads and the telegraph made transportation and communication faster, it became more and more difficult to handle all the different times. It's confusing enough with about 40 time zones around the world; imagine when there were thousands!
Railroads.

Railroads
Railroads, but notably the corruption within the transportation industry.
Trucks may be used as well as airplanes. It really depends on where exactly the frigid zone is.
Communication and transportation were so slow that it didn't matter that every city was on a different time.
Time zones were originally set up by the railroads to simplify train scheduling. It didn't take long for other modes of transportation to see the advantages. Then the countries had to agree on standard time zones suitable for their situations.
temperate zones
The earth is divided among 40 time zones (not 24) because before standard time started catching on in the late 1800s each of the thousands of cities kept its own time, and that started to get confusing as technology started making transportation and communication faster.

Time Zones?
The roads are not specified on any online source. However, there is transportation via train to and from the different zones, i.e olympic zone, central zone, and river zone.
