 Time zone - Art History Online Reference and Guide
Time zones are areas of the Earth that have adopted the same standard time, usually referred to as the local time.
Time zones are generally centered on meridians of a longitude that is a multiple of 15° thus making neighboring time zones one hour apart.
Time zones were first proposed for the entire world by Canada's Sir Sandford Fleming in 1876 as an appendage to the single 24-hour clock he proposed for the entire world (located at the center of the Earth and not linked to any surface meridian!).

A compromise time scale was eventually devised, and on January 1, 1972, the new Coordinated Universal Time (UTC) became effective internationally.
Interestingly, the standard timekeeping system related to this arrangement of time zones was made official in the United States by an Act of Congress in March 1918, some 34 years following the agreement reached at the international conference.

The Time and Frequency Division, part of NIST's Physics Laboratory, maintains the standard for frequency and time interval for the United States, provides official time to the United States, and carries out a broad program of research and service activities in time and frequency metrology.
The division develops and maintains the primary standards for frequency and time interval in the United States.
NIST researchers are also demonstrating the potential to fabricate and assemble the physics package using the low-cost, mass-production techniques used to make semiconductor devices, which should eventually lead to a complete atomic clock about 1 cubic centimeter in size (about the size of a pencil eraser) powered by a battery.

Over time more articles will be added, to cover additional topics and expand on the existing ones.
Until late 1912 there was no licencing or regulation of radio transmitters in the United States, so amateurs -- known informally as "hams" -- were free to set up stations wherever they wished.
But with the adoption of licencing, amateur operators faced a crisis, as most were now restricted to transmitting on a wavelength of 200 meters (1500 kilohertz), which had a limited sending range.
