getItemPublishDate :: ParseTime t => ItemGetter (Maybe t) Source

'getItemPublishDate item' returns the publication date of the item, but first parsed per the supported RFC 822 and RFC 3339 formats.

If the date string cannot be parsed as such, Just Nothing is returned. The caller must then instead fall back to processing the date string from `getItemPublishDateString`.

The parsed date representation is one of the ParseTime instances; see `Format`.
