The {{Information}} template value for DateTimeOriginal is parsed correctly in multilang mode but ignored in single-language mode:

http://commons.wikimedia.org/w/api.php?action=query&format=jsonfm&prop=imageinfo&titles=File%3APelican_in_its_piety%2Ejpg&iiprop=extmetadata&iiextmetadatafilter=DateTimeOriginal&iiextmetadatamultilang=1

"DateTimeOriginal": {
    "value": "<span style=\"white-space:nowrap\"><time class=\"dtstart\" datetime=\"2006-03-25\">25 March 2006</time></span> (original upload date)",
    "source": "commons-desc-page"
}

(correct)

"DateTimeOriginal": {
    "value": "2006:03:19 10:29:45",
    "source": "file-metadata"
}

(incorrect, falls back to EXIF value)
