PBS - How We Got to Now (2014) Part 2 Time

How We Got To Now with Steven Johnson reveals the story behind the remarkable ideas that made modern life possible; the unsung heroes that brought them into the world – and the unexpected and bizarre consequences each of these innovations has triggered.

Part 2: Time

Board a submarine with Steven Johnson to discover what a lack of natural light means for a sailor’s working day and visit Heathrow, the world’s busiest airport, to try to get timings right at air traffic control. The story of getting a grip on time is full of curious garage tinkerers. One of them, railway clerk William F. Allen, was so exasperated by the chaos caused by the hundreds of local times zones in the U.S. that he fought tirelessly to standardize time into four zones. Learn how advancements in navigation, the way we work, technology and travel would have been impossible without the unsung heroes of time.
