A large clock discontinuity (reset) of about 514 microseconds was detected
for PRN30 at approximately 22:20 on day 353.

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.)
