    Re: Extremely poor conditions??Atomic Clocks

    You can find details on how WWVB transmits the time at
    http://www.nist.gov/pml/div688/grp40/wwvb.cfm
    Summary: it sends the complete time and date every minute, but the coding doesn't include any form of error-correction. Dropping one bit of data could certainly make a clock lock on to a time that's off by 1 minute (or 2, or 4, or 8, or 1 day, etc). But I would expect a well-designed clock to gather data for several minutes and check it for consistency -- there's plenty of redundancy if you do that!
