In order to deserialise and re-serialise dates and date times from tags properly, we need to be able to express partial dates (e.g. YYYY or YYYY-MM) and date times. We only support partial date times where all the more significant fields above the first unset field are set (e.g. YYYY-00-DD is not supported). Calling _get_foo() when foo is not set is not allowed any more, callers need to check which fields are set first. https://bugzilla.gnome.org/show_bug.cgi?id=677757
