What proves you wrong about the time involved is this historical fact:
the death of Christ happened at the passover in the month Nisan, in the four thousand seven hundred and forty-sixth year of the Julian period. Four hundred and ninety years, reckoned back from the above year, leads us directly to the month Nisan in the four thousand two hundred and fifty-sixth year of the same period; the very month and year in which Ezra had his commission from Artaxerxes Longimanus, king of Persia, (see Ezr 7:9), to restore and rebuild Jerusalem. See the commission in Ezra 7:11-26, and Prideaux’s Connexions, vol. 2 p. 380.
The prophecy was fulfilled 490 years after the command to rebuild and restore Jerusalem was given, not 490 days.
You most definitely need to rethink your eschatology.
