Games open with football, Bolt says "this is my time"

CARDIFF/LONDON (Reuters) - The British and New Zealand women's football teams kicked off the Olympics on Wednesday as the sporting action began, and Jamaican sprinter Usain Bolt, hero of the Beijing Games and the fastest man on earth, vowed to win again, declaring: "This is my time".

The whiff of scandal hung over London's Olympic Park, where thousands of journalists and athletes were limbering up for the July 27-August 12 showcase, after Greek triple jumper Paraskevi Papachristou was withdrawn from the Games for a racist tweet.
