Another time they argued "time." Sure, Greenwich time bears no relation to lunar. But why should it when we live Underground? Show me a Loonie who can sleep two weeks and work two weeks; lunars don’t fit our metabolism. What was urged was to make a lunar exactly equal to twenty-eight days (instead of 29 days, 12 hours, 44 minutes, 2.78 seconds) and do this by making days longer—and hours, minutes, and seconds, thus making each semi-lunar exactly two weeks.
