Exact Timing for the Rapture

While we do not know the exact time we are charged to know when Jesus is at the door.
The bible says that the generation will not pass that see the fig tree blossom..the fig tree being Israel.
This happened in 1948 May 15th.
A generation in the bible can be interpreted as anywhere from 40 to 120 years.
So if we take the maximum 120 we come to a year of 2068.
It is interesting that Sir Issac Newton predicted the year 2060!!!!
Again the rapture can happen anytime but this gives us some idea of the timing.
