There's no particular name for it (AFAIK), but FFT theory will provide
a solution. If you want to think about it, I can give you two hints:

* It's related to the sin() vs. cos() thing mentioned earlier.
* In this particular case there's an extra twist to it - think
  of shifting a cyclic waveform in time by half a sample.
