identity_export_year() was a bit short-sighted. We really require arbitrary date ranges. A new function was created to tackle this - channel_export_items() which takes a channel, and a start and finish date. Finish date will default to "now" if not set. Will be working this into the interface under a module named "export_items" which will correspond closely to the existing "import_items" module you'll need to do the reverse operation. Will also make it available via the API. Once that is complete, I anticipate removing identity_export_year() as it will then be somewhat redundant, and modifying the documentation on the channel export page accordingly. Note: the function works strictly in GMT so an interface would need to convert from channel local time.
