In this format we use one record to represent one day's data. The record length of 128 bytes is divided thus:

              format
 
       1-  4    I4    Year
       5-  6    I2    Month
       7-  8    I2    Day
       9- 13    A5    Characteristic value for 0000 local mean time
      14- 18    A5    Characteristic value for 0100 local mean time
       ..       ..          ..
     124-128    A5    Characteristic value for 2300 local mean time

Each characteristic value is represented by 5 characters in the international standard code described in report UAG-23A.
