Modify the Olson time zone database

To modify the Olson time zone database

1. Update the %DataDir%\Shared\sdk\3rdParty\ZoneInfo\tzdata\ file.

   For example, to update the MST time offset from -7:00 to -10:00:

   1. Locate the config in C:\AVEVA\DNA\Shared\sdk\3rdParty\ZoneInfo\tzdata\northamerica.

   2. Change the offset value from -7:00 to -10:00 and save the file.

      For example:

      #Zone NAME STDOFF RULES FORMAT [UNTIL]

      Zone EST -5:00 - EST

      Zone MST -10:00 - MST

      Zone HST -10:00 - HST

2. Open a Windows Command Prompt.

3. Change the working directory to the %DataDir%\Shared\sdk\3rdParty\ZoneInfo\tzdata\ folder.

4. Execute the zic.exe command to generate the updated time zone databases:

   <full path>\zic.exe -d ..\DB northamerica

   The output of the compilation is a set of binary data files, which are saved to the %DataDir%\Shared\sdk\3rdParty\ZoneInfo\DB\ folder.

   Note: Only the binary data files for northamerica files are updated.

5. Follow the instructions in Deploy the Olson time zone database to deploy the Olson time zone database to all servers.
