   I don't see any advantage of using GPS vs. radio signals to keep clocks   
   and wrist watches properly set in almost all areas of the continental   
   US, Japan, or western Europe where there are time calibration radio   
   signal transmitters.  No lay citizen needs to have their timepiece set   
   with the accuracy of a fraction of one second.  No unobstructed view of   
   the sky is required with radio signal calibration.  My "atomic" wrist   
   watch and clocks are kept in locations that no view of the sky and they   
   receive the radio signals despite screens on the windows, steel girder   
   building construction, and my condo unit on a lower floor where   
   surrounding buildings at all points of the compass are far higher.  That   
   feature makes radio signal calibration much more practical for the lay   
   citizen, especially those who live in urban settings with many tall   
   buildings that are likely to prevent a clear view of the sky. Where GPS   
   comes into it's own is in locations where time calibration radio signals   
   are not available, or for applications where maximal precision of   
   timekeeping is essential.  Ideally, the timepiece would include the   
   ability to switch between radio signal reception and GPS reception at   
   the discretion of the user.  Bulkier and more expensive, but with   
   essentially total planet capability for automatic, accurate time keeping.
