> Note: The formatter component is designed to format values to be displayed for the end user. If you want
> to convert user input into machine readable format, or just format a date in a machine readable format,
> the formatter is not the right tool for that.
> To convert user input for date and number values you may use [[yii\validators\DateValidator]] and [[yii\validators\NumberValidator]]
> respectively. For simple conversion between machine readable date and time formats,
> the PHP [date()](http://php.net/manual/en/function.date.php)-function is enough.
