A clock discontinuity (reset) of about 5 microseconds was detected for
PRN21 at approximately 06:35 on day 010.

Due to potential problems, data from stations mentioned below were not
considered for use in the global solution for the day indicated.  (For
geographical reasons, they may not have been used in any case.)
