    Time and cel nav, a stupid question
    From: Bill B
    Date: 2008 Apr 22, 02:53 -0400

    The current discussion on time, relativity and leap seconds is, in many
    areas, well above my head.  Noting the various flavors of UT (currently), an
    observation and a pragmatic question for cel nav.
    
    The seconds readout between my GPS (Garmin GPS 76) and
    http://tycho.usno.navy.mil/cgi-bin/anim
    differ by about one (1) second.
    
    The web site (dial up modem at the moment) is nominally one (1) second
    behind the GPS readout.
    
    Bringing it into the realm of traditional navigation, which time do I use to
    set my hack watch? ;-)  Potentially a quarter mile intercept difference
    under ideal circumstances.
    
    I do not have access to a time-signal radio now.
