I consider the switches to and from Daylight Savings Time to be largely useless in the modern era. It disrupts sleep patterns, causes people who forget to adjust clocks to miss appointments, and adds something else to worry about to our hectic lives.

(Of course, I may be grumpy because it really threw off the sleep cycle of our children, causing a few long nights with overly tired children and bad dreams.)
