I have a clock radio controlled by the atomic clock and, as of Monday, it still had not changed to the daylight-saving time. Why is that? According to the Time and Frequency Division of the National ...

Deep in the Colorado foothills, there are two radio transmitters that control the time on millions of clocks all across North America. It’s WWVB, the NIST time signal radio station that sends the time ...

The advantage of a radio-controlled clock that receives the time signal from WWVB is that you never have to set it again. Whether it’s a little digital job on your desk, or some big analog wall clock ...

NIST is changing the way it broadcasts time signals that synchronize radio-controlled "atomic" clocks and watches to official US time in ways that will enable new radio-controlled timepieces to be ...

I never dreamt it would be possible to read the time and room temperature on my ceiling. Then a friend gave me a gadget for doing just that. The Ambient Weather RC-8427 Clearview Radio Controlled ...

Many people will wake up with an alarm clock with an alarm clock, but if the clock goes wrong, there is a risk that the schedule for the day will be off, so you want to choose a clock that is as ...

From Rhythm Watch Co comes this radio-controlled alarm clock that uses an analog thermometer face. Movement of the second hand stops at night, assuring a quiet sleep environment without disturbing ...

A popular project among microcontroller aficionados is to build a radio-controlled clock. Tiny receiver boards are available, with a pre-adjusted ferrite antenna, that receive and demodulate the DCF77 ...

The following is an extract from our Lost in Space-Time newsletter. Each month, we hand over the keyboard to a physicist or two to tell you about fascinating ideas from their corner of the universe.
