Not to the JWs since the invention of the elastic generation i imagine. They have largely forgotten that teaching.
But to a JW offshoot that targets JWs it sure does! (Source; The Lords Witnesses website).
On 2009July18, the UK WW1 Veteran, Henry Allingham died aged 113 (the oldest man in the world at that time).
Florence Beatrice Green who became 110 on 2011February19 is the only surviving WW1 veteran as of 2011May8.
The life expectancy of this pair is less than 2 years.
Then on 2011May5 Claude Choules died in Australia. So today we have one WW1 veteran left, Florence Beatrice Green who is 110 years old. The oldest man in the world is normally 113 and the oldest woman is normally 115. Florence's life expectancy of the entire list above is around 2 years. The oldest male in the world is generally between 111 and 114 year old.
That means Jesus must come and the Great Tribulation must occur and the end must come in the next 3 years and should be expected within 2 years.
