Sun!

As I was laying in my bed last night (which is where I do my best thinking) I thought: "Is daylight savings time really an hour ahead or is it actually the real time?" We change our clocks back but then we put them an hour forward again so which one is the real time? Is it really supposed to be dark at 6 o' clock or is it actually the other way around?! That's a great way to confuse yourself...
