You might think of William Willett, who invented daylight savings time. He suggested that clocks be moved forward by 20 minutes in April, which would then be reversed in September. He claimed that lighting costs would be reduced, which would have benefits.

Arthur Conan Doyle, Sherlock Holmes author, argued that it would be easier to reverse and advance clocks by one hour instead of four increments like Willett suggested.
