Green_Hilltop: When DST ends you roll clocks one hour back. So if you use DST, you always roll one hour forward, and then half a year later, one hour back.
DaCostaBR: I know, but he said "it's 4pm and it's already dark because the sun thinks it's 5pm", that's what confused me, since it's either 4pm and the sun thinks it's 4pm in regular time or it's 5pm and the sun thinks it's 4pm in DST. The way he said it made it sound like the clock was set back an hour from the actual solar time.
Which it is, since you actually have it the other way around - and so did I, because you roll back clock when DST starts, not when it ends (I forget which is which, since the net takes care of it for me). So when DST starts you lose the hour, while in regular time you have one more hour than you have now if you're using DST - so that in wintertime you have sun when you're waking up instead of darkness (so when it's 6AM in regular time, it's 5AM in DST).
So he's right - the sun thinks it's 5PM (solar/regular time), but in DST it's 4PM.
