function date_formatter_process

Helper function for creating formatted date arrays from a formatter.

Use the Date API to get an object representation of a date field.

Parameters

string $formatter: The date formatter.

string $entity_type: The entity_type for the instance

object $entity: The entity object.

array $field: The field info array.

array $instance: The field instance array.

string $langcode: The language code used by this field.

array $item: An entity field item, like $entity->myfield[0].

array $display: The instance display settings.

Return value

array: An array that holds the Start and End date objects. Each date object looks like: date [value] => array ( [db] => array ( // the value stored in the database [object] => the datetime object [datetime] => 2007-02-15 20:00:00 ) [local] => array ( // the local representation of that value [object] => the datetime object [datetime] => 2007-02-15 14:00:00 [timezone] => US/Central [offset] => -21600 ) )
