Only a very rough guesstimate - based on my "Phil's best guess" idea that the rapture will occur after the first 3 1\2 years of the tribulation period.

I also guess that the current world order would take a good few months to bring in the Antichrist figure - who starts off the 7 year Tribulation period by making an agreement with "many" - my guess is that this is between the Israelis and Arabs, allowing a temple to be built on the Temple Mount.
So 3 1\2 years plus a number of months - getting close to 5 years minimum before you get your resurrection body!
