Some people in this thread seem to be taking this story at face value, astoundingly. Let's be clear: "Time working differently inside the tunnel" is, with 100% certainty, not was was going on. More plausible (not mutually exclusive) explanations: - The workers messing with each other (and possibly their bosses) to have a laugh and/or forge work hours - There was a bike hidden in the tunnel - The workers were coordinating with each other by radio or by phone - It didn't take as long to traverse the tunnel as people really thought - Without daylight cues, it became very easy to lose track of time - The workers were surprised or confused by ultimately ordinary circumstances, and a mystical explanation spread and socially validated itself, bolstered by the power of suggestion.
