Bug report: wrong sign in the Fourier transform?

Wolfram Alpha is going to use Mathematica for the computation. The documented behavior for Mathematica is quite easy to find by web search. Here is the relevant link.

Click on Details and Options opener to see information on definition used and parameter settings.

Dear Daniel,

Many thanks for the quick reply! Sorry for the stupid question. I see now, this is not a bug, the exponent in the Fourier transform is simply exp(+iwt), not exp(-iwt) as I assumed!

Best regards, /Alexey
