    Re: Radio Synchronized Clock
    From: Steven Wepster

    Dear Brian,
    
    Sorry I did not get your intention straight away. Yes, I agree with you
    that radio clocks are very likely only useable within a limited range, and
    therefore I prefer to take a quartz watch that I keep at wrist temperature
    and that has a known rate.
    
    Steven.
