Is the OP asking the exact time and date and minute and second when the world became corrupted, well I wasnt there at the time so, cant pinpoint it, but maybe it was when adam and eve ate the forbidden fruit and their eyes were opened and they saw they were naked.
Before that they were naked and it didnt bother them, but after they saw they were naked and it did.
I would offer before they sinned being in the presence of God as children of light they must had a glow like that of Moses when he came down from mount Sinai. When they sinned their corrupted body lost that covering representing the righteousness of Christ, as the glory of God. .
They covered up their private parts in shame, this was on the sixth day. (for husband and wife eyes only) Most likely the rest of creation had already been subject to corruption . God setting a side a special place in a garden in an already perfect creation to be used as a parable.
I would offer that the father of lies as the unseen spirt of error, Lucifer was the cause of corruption, this is when Christ found pride in his heart. Maybe all in the twinkling of the eye as soon as he created him . Up until day four the glory of God was the light of this world and then God turned on the switch of the two temporal time keepers the Sun and the moon.
In the new incorruptible heavens and earth . God again will be the source of light just as during the first three days .Three as usual denoting the end of the matter. .
And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it.And the city had
no need of the
sun, neither of the
moon, to shine in it: for the
glory of God did lighten it, and the Lamb is the light thereof. And the nations of them which are saved shall walk in the light of it: and the kings of the earth do bring their glory and honour into it.Revelation 21:22-24
