LONDON, Oct.24 (Xinhua) -- A three-man team with time on their hands on Saturday started a massive task of altering London's famous Big Ben clocks along with more than 2,000 other timepieces around Britain's houses of parliament.
The end of British Summer Time (BST) at 2:00 a.m. on Sunday means every clock in the country will have to be adjusted back by one hour when time reverts to GMT.
