Among the measures of the German administration was to shift Belgium from Greenwich Mean Time to Central European Time. Before the War Belgium was the sixth largest economy in the world but the Germans destroyed the Belgian economy so thoroughly by dismantling industries and transporting the equipment and machinery to Germany that it never regained its pre-war level. More than 100,000 Belgian workers were forcibly deported to Germany to work in the war industry and to Northern France to build roads and other military facilities to the German military's benefit.[3]
