Japan rail firm apologises after train leaves 20 secs early

A Japanese rail company has apologised after one of its trains departed at 9:44:20 am instead of 9:44:40 am local time, 20 seconds ahead of schedule. It said the conductor had not checked the train timetable properly, adding that crew were given additional training to prevent a recurrence. Notably, no one missed the train due to the early departure.
