This article details a time synchronization service from NIST, rather than a quantum computing standard. It explains how users can access radio time signals via telephone to synchronize clocks and timers, with the service currently active and receiving about 1,000 calls daily. This system is designed to help maintain precise timekeeping for various devices using the WWV and WWVH broadcast stations.
The summary highlights that landline calls within the U.S. offer high stability with minimal delay, while mobile or satellite connections may introduce latency. Callers can dial specific numbers for stations in Colorado or Hawaii, though the service is not toll-free and automatically disconnects after two minutes. This ensures users understand the reliability and limitations of the connection method when relying on this timing signal for accuracy.
