Why does the tabs here at UG show standard tuning for this song?

I was just figuring it out - the first notes are D#, not open E like the tabs. I've played it in drop D which sounds right and standard tuning which doesn't sound right at all.

Am I right? This is a drop D tune right?
ok, I'm gonna guess that the tabs just don't specify drop D and my tuning was 1/2 step too low, so I had to fret at the first fret to get up to D (which I thought was D#).
