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. </commit_message> </commit_message> </commit_message> This ensures the data is correctly formatted for easier handling and prevents potential runtime errors when reading timezone data. </commit_message>
