[...] Still, standardization was a slow process—and one that faced some resistance. Railways in the US and Canada coordinated clocks in November 1883. But the city of Detroit, for example, clung to sun time. In 1900, the Detroit City Council ordered that clocks be adjusted 28 minutes to abide by Central Standard Time. Citizens refused, however, and the decision was rescinded.
In fact, uniformity wasn’t established in the US until 1918, when the Standard Time Act passed. Today, there are 37 different local times in use around the world.
Now, technology is changing our relationship with time again. In Britain, schools are removing analog clocks from exam room walls, replacing the traditional round-faced tools with digital timepieces, which are easier for postmodern students to read. Malcolm Trobe, deputy general secretary at the Association of School and College Leaders, told The Telegraph in April, ”You don’t want them to put their hand up to ask how much time is left.”
