8/21/99 to 8/22/99"?  What's that?
        \_ Some rocket scientist in the DoD defined GPS to only have a 1024
           week counter, starting in 1980, which rolls over to 0 again at
           midnight on 8/22/99.  For more info, see:
                   <DEAD>www.navcen.uscg.mil/gps/geninfo/y2k<DEAD>
           \_ Older GPS receivers only allotted 10 bits to the calendar
              function. Those receivers will rollover again in like 2018.
              Most GPS receivers in military use and deployed on
              spacecraft do not have this problem. --dim
