when i checked the output using cdo sinfo, the result of EA22082218
is:

Time coordinate :
                             time : unlimited steps
 RefTime =  2022-08-22 18:00:00  Units = hours  Calendar = proleptic_gregorian
  YYYY-MM-DD hh:mm:ss  YYYY-MM-DD hh:mm:ss  YYYY-MM-DD hh:mm:ss  YYYY-MM-DD hh:mm:ss
  2022-08-22 18:00:00  2022-08-20 03:00:00  2022-08-20 06:00:00  2022-08-20 09:00:00
  2022-08-20 12:00:00  2022-08-20 15:00:00  2022-08-20 18:00:00  2022-08-20 21:00:00

the time stamp with 2022-08-22 18:00:00 is acceptable, but other time stamp is strange. Why there exist the 2022-08-20 time stamp.
