Call to undefined function system_date_format_locale()...

Got this message when trying to save a node with a Date field.

Looks like you just need to change

$format = system_date_format_locale($langcode, $format_type);

in date_formatter_format() to

$date_format = system_date_format_load($format_type);
$format = isset($date_format['locales'][$langcode]) ? $date_format['locales'][$langcode] : $date_format['pattern'];

as per https://api.backdropcms.org/node/41663
