In addition to increased accuracy, the development of chip-scale atomic clocks has expanded the number of places atomic clocks can be used. In August 2004, NIST scientists demonstrated a chip-scale atomic clock that was 100 times smaller than an ordinary atomic clock and had a much smaller power consumption of 125 mW .
As a further extension of the information content transmitted by DCF77, appropriately equipped radio clocks can provide a four-day weather forecast for 60 different regions in Europe. The forecast data is provided by and under responsibility of the Swiss company Meteo Time GmbH and is transferred in a proprietary transfer protocol.
La Crosse Technology introduced the radio-controlled clock, commonly (but incorrectly) called an "atomic clock" after the extremely accurate timepiece behind the radio signal it uses as a reference, into the United States commercial market in 1991. [3] [4] In 2004, the company was awarded a license to sell The Weather Channel branded weather ...

The expected performance of a single-ion nuclear clock was further investigated in 2012 by Corey Campbell et al. with the result that a systematic frequency uncertainty (accuracy) of the clock of 1.5 × 10 −19 could be achieved, which would be by about an order of magnitude better than the accuracy achieved by the best optical atomic clocks ...
