WWVB's Colorado location makes the signal weakest on the U.S. east coast, where urban density also produces considerable interference. In 2009, NIST raised the possibility of adding a second time code transmitter, on the east coast, to improve signal reception there and provide a certain amount of robustness to the overall system should weather or other causes render one transmitter site ...
This split reduced 303 to the Denver-Boulder area. [3] With the 1995 split, 303 was the only Colorado area code that did not border another state. Within two years, continued sharp growth in the Front Range made further relief necessary. The Front Range is home not only to most of Colorado's landlines, but also most of the state's cell phones ...

NIST-F1, source of the official time of the United States. NIST-F1 is a cesium fountain clock, a type of atomic clock, in the National Institute of Standards and Technology (NIST) in Boulder, Colorado, and serves as the United States' primary time and frequency standard. The clock took fewer than four years to test and build, and was developed ...
Boulder is a home rule city in and the county seat of Boulder County, Colorado, United States. [1] With a population of 108,250 at the 2020 census, it is the most populous city in the county and the 12th-most populous city in Colorado. [6]
WWV Transmitter Building (2002 or earlier) WWV's 15 MHz antenna WWV is a shortwave ("high frequency" or HF) radio station, located near Fort Collins, Colorado.It has broadcast a continuous time signal since 1945, and implements United States government frequency standards, with transmitters operating on 2.5, 5, 10, 15, 20, and 25 MHz.

Time zones were therefore a compromise, relaxing the complex geographic dependence while still allowing local time to be approximate with mean solar time. Railroad managers tried to address the problem by establishing 100 railroad time zones, but this was only a partial solution to the problem.
