More Every Day Accurate-to-the-Minute Clocks in our Lives : * Home Computer Clocks - Self-Setting * Telephone and Celphone Clocks - Self-Setting * Cable TV "Set-Top-Box" Clocks - Self-Setting * The Clock you "See" on the TV - Self-Setting * The Top-of-the-Hour (TOH) "'Tone" you Hear on the Radio be it AM -or- FM -or- even a Shortwave Radio Broadcast. CLOCKS - We Take them for Granted -but- They Are There Day-after-Day : Accurate-to-the-Minute i am sure there are a few more to add to the list ~ RHF |

You should be able to find software utilities that connect to web sites with atomic clocks. That would be best. There might even be some free utilities that query time servers. -- Telamon Ventura, California |

They might speed up for a while, but then they slow down to compensate (and vice versa). The Drake R8B clock synchronizes to the power lines, as do many alarm clocks. |

I believe it is WWVB that sends the signal and not WWV but the difference is not relevant. Not relevant? How so? The FCC would fine them if they misidentified so there is at least some relevance on some level. As far as I know there's WWVB and a station in Germany. The cheapest most accurate clocks are the ones that use the AC mains for a timebase. Actually the clocks with the most accurate display would be those that synchronize daily with a time standard. That would include Atomic (radio) Clocks and PC Clocks. Find me a PC for under $10. Same for an atomic watch. And there are many PCs that wander 10 seconds or more between NTP updates. The traditional synchronous clock is the champion for staying on the correct time the best over an extended period of time, without a reset of some kind. Try to pay attention sparky. The thread is about quartz clocks being sucky. |
