How do time zones work? Perhaps equally important is why do we even have time zones? The BBC News group has created this interactive and fun exploration of time zones for the general public. After a brief introduction, visitors can continue on to a globe complete with tabs that read, "Where time collides", "Split time", "The politics of time", and "What time is it in space?" Clicking on each of these tabs will bring up a short video that illuminates each of these questions. Moving along, visitors should definitely click on "The science of time" for BBC reporter Rebecca Morelle's investigation into how time is measured. Also, visitors shouldn't miss the "Time zones: Your experiences" area, as it offers insightful commentary on people who regularly travel across many time zones or who need to contact family members around the world.
