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.
