wp_get_media_creation_timestamp( array $metadata )

Parse creation date from media metadata.

Description

The getID3 library doesn’t have a standard method for getting creation dates, so the location of this data can vary based on the MIME type.

Parameters

$metadata

(array) (Required) The metadata returned by getID3::analyze().

Return

(int|false) A UNIX timestamp for the media's creation date if available or a boolean FALSE if a timestamp could not be determined.
