A clock discontinuity (reset) of about 29 microseconds was detected for PRN29
at approximately 21:50 on day 163.

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.)
