The Qur'an says that the Hour will come ALL OF A SUDDEN--when people would NOT BE EXPECTING it! If these ahadith are true, then we should rest assured that the Day of Judgment is NOT coming anytime soon because no Qaim (Mahdi) has come yet, no Jesus has shown up yet, and large preponderance of women over men have not occurred yet (1:50 man/women ratio---according to some reports).
The sign of the Hour is ONLY known to Allah and the Qur'an says that the "tokens thereof (Hour) have already appeared". That means we should always remain at the edge of our toes for the Hour!!!
(Sorry, I don't have refs of the verses I referred to in my office but I am sure I can post from home in case this needs to be done)>
