The commit fixes issues in the `Country` model to properly handle
timezones when it's a string. The change processes the content and
parses it as JSON data, and fixes an issue with JSON format.
- The `format_timezones` method now attempts to parse and reformat
timezones to prevent potential JSON parsing errors.
- If the conversion to JSON fails, logs the error.
- The code ensures data integrity
by parsing and reformatting the JSON for timezone data to solve a
bug.

and prevents potential runtime errors when reading timezone data.
