A clock discontinuity (reset) of about 631 microseconds was detected for
PRN22 at approximately 00:00 on day 078.

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.)
