function date_field_formatter_view

Implements hook_field_formatter_view().

Useful values:

$entity->date_id If set, this will show only an individual date on a field with multiple dates. The value should be a string that contains the following values, separated with periods:

• module name of the module adding the item
• node nid
• field name
• delta value of the field to be displayed
• other information the module's custom theme might need

Used by the calendar module and available for other uses. example: 'date:217:field_date:3:test'

$entity->date_repeat_show_all If true, tells the theme to show all the computed values of a repeating date. If not true or not set, only the start date and the repeat rule will be displayed.
