The concept has existed since at least 1858 in an obscure writing, but it didn't get worldwide agreement until 1884.
When time zones were adopted universally, time anywhere on the world became standard.
The world time zones were officially adopted at the International Meridian Conference in 1884. This marked the establishment of 24 time zones, each one hour apart, with the Prime Meridian at Greenwich, England as the starting point for measuring longitude and time.

There are 24 time zones established worldwide, each representing a one-hour difference from the next. These time zones help coordinate and standardize timekeeping across different regions.
Time zones were adopted to create a standardized system for organizing and measuring time across different regions. This system helps to avoid confusion and facilitate coordination in a globalized world by ensuring that everyone can refer to the same time regardless of their location. Additionally, time zones help to synchronize activities such as transportation schedules, international communication, and business operations.
There are 39 time zones because the Earth is divided into 24 longitudinal sections, each representing one hour of time difference. However, some regions choose to use a half-hour or quarter-hour offset from neighboring time zones, leading to 39 distinct time zones worldwide.
There is no US state that officially spans more than 1 time zone.
Time zones were officially established in the US on November 18, 1883 by the railroads in order to standardize schedules. This was known as the Standard Time Act, which divided the US into four time zones: Eastern, Central, Mountain, and Pacific.
The International Telecommunication Union (ITU) is the organization that determines and regulates worldwide time zones. The ITU coordinates with countries to establish and maintain accurate timekeeping standards for different regions.
