Your interpretation of Zechariah 7:1-5 is preposterous as it is without foundation and contradicts both Scripture and well established history. The Bible indicates quite clearly that the seventy years ran until the royalty of Persia began to reign when in Cyrus first year (537) released the exiles from Babylon. The fact that Darius 1 is ruling at that time establishes that the seventy years had aleady concluded some twenty years earlier when Daniel had correctly discerned in the first year of Darius the Mede that the seventy years had ended (Daniel 9:2).There is nothing in either Zechaiah 1:7,12 and &:1-5 to suppose that the seventy had not concluded but were according to some in continuation, It is ovbviuos that the seventy years referred to belongs to the past and not to the present.
All you are doing is simply rehashing Jonsson who discusses this subject on pp.226-8 in GTR 1998. In response you should read what Rolf Furuli says about this matter in pp.67-9 in his Persian Chronology And The Length Of The Babylonian Exile Of The Jews, 2003.
