It also doesn't save any energy. One article I read stated that DST costs around 1% more energy than standard time and several countries are considering ending the practice.
As to the poster who said kids would go to school in the dark if it wasn't for DST has it turned around. For the past several weeks, the kids were catching the bus at sunrise until tomorrow when it will be pitch black. Besides messing with our internal clocks, it makes it more dangerous for commuting in the morning.
