I recall reading that, at some point, the hour meters were reporting actual engine hours (from the ECU) versus time key is on. If that's not the case with this one, you should be able to just hook it up to a battery and disconnect it in 12+ days when the hours are correct. Just be sure to set a reminder to disconnect it.
