[IGSSTATION-7170] - 2017-11-22 (05/12/2017)

The "TIME OF FIRST OBS" field in the headers for KGNI and KSMV during DOY
314 - 324 has been incorrect.
We have already uploaded the data sets which have correct headers to CDDIS
and KASI. In addition, we have added the signal-to-noise (S1 and S2) into
the OBS files since DOY 314.
The correct data files have been put on SONEL on 2017-12-05.

The data sets of Koganei (KGNI) and Kashima (KSMV) from DOY273 until
DOY295 have been sent to CDDIS and KASI server today. Our data server
has been stopped until today due to Shellshock problem. The bash of the
server has already been updated. Unfortunately, since some data sets
corrupted, these were lost. The lost data sets are
