Daylight saving time is a good idea.
Changing all the watches in U.S. (first forward one hour, then backward one hour) once every year are formidable tasks that involve our governments, thousands of companies and millions upon millions of individuals. The U.S. could save in the billions of dollars each year of we computerized this procedure.
Today, millions of people in U.S. must spend time to manually change all the clocks in their individual homes, in factories, offices, buildings, etc. Our government could have satellites that on a timely date broadcast the resetting of clocks one hour forward or backward.
Companies can manufacture cheap clocks that can receive messages from our satellites, and execute the requested change to watches within the geographical area that is being addressed. Manufactures can also produce wristwatches, room clocks, computer clocks, etc. that can receive the “time signals” broadcasted from satellites.
That is how easy the world should be.
