When exporting transactions from Piere, the date field currently includes a timestamp. Many budgeting and financial tools expect dates in a clean yyyy-dd-mm format (without a timestamp) for easy import and compatibility. It would be helpful to either export dates in yyyy-dd-mm format by default, or allow users to choose their preferred date format when exporting transactions. This would make it easier to move data between Piere and other budgeting tools without needing to manually reformat the date column.
