I do not know. Probably for some historical reasons. In Clipper the
result of _itemGetNL( pDateItm ) is undefined and tests confirm it.
But _parnl( iParam ) seems to return Julian date when iParam is date
item. Probably some of conversions we have in hb_itemGet*() functions
are used to emulate unprotected access to ITEM internals in Clipper
in _itemGet*() functions. But I cannot say which ones and which were
added by Harbour developers as some type of Harbour extensions.
