Unfortunately, I can't replicate the problem. All post and thread times are showing correctly for me so I can only assume that the problem is possibly something to do locally with your computer.
In the scheme of things, perhaps we should remember the old adage that "worse things happen at sea".

NO worries, as I said I have stoopped worrying about it, just I like things to work properly.
That is why I never go on ships.
Enjoy your holiday in Jamaica.
