A large clock discontinuity (reset) of about 21 microseconds was detected
for PRN21 at approximately 14:40 on day 019.

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.)
