Different towns all used local time, which made operating a railroad system impossible. Creating time zones put all places within the zone on a common time.
When time zones were adopted universally, time anywhere on the world became standard.

Rift zones are formed on Earth's surface due to tectonic plate movements where the plates are pulling apart. They are made of volcanic rocks, such as basalt, as magma rises to the surface through fractures in the crust. Rift zones are characterized by intense volcanic activity, earthquakes, and the creation of new crust.
These zones are known as subduction zones where tectonic plates collide, forcing one plate to be pushed beneath the other. This process leads to the formation of deep ocean trenches and can result in earthquakes, volcanic activity, and the creation of mountain ranges.
Explosive volcanoes are most common at subduction zones.
Divided the United States into time zones
When time zones were adopted universally, time anywhere on the world became standard.
Its because they are zones/areas of new crustal formation/creation.

Human activities such as agricultural run-off, industrial discharge, and sewage dumping can contribute significantly to the creation of dead zones. These activities introduce excess nutrients like nitrogen and phosphorus into water bodies, leading to algal blooms. When these algae die and decompose, they deplete oxygen levels, creating dead zones where marine life cannot survive.

In the United States, the creation of standardized time zones greatly improved the ability to schedule train times and to manage train movements.

Cholera is spread by sewage-tainted drinking water. Cholera can become a problem anyplace that basic sanitary services cannot be provided. Disaster zones, war zones, wilderness areas; anything that interrupts the handling of sewage and the supply of clean drinking water can spread cholera.
Could be either, depends on the type of system.
