 Damn, everything starts from 0, so i automatically put '0 - 32'. The actual time, however, varies from 1 to 32, but the value is
from 0 to 31, i. e. <time> - 1
 What shall we do? Just document this, or adjust the code to take number of cycles and subtract 1? To tell the truth, i'm already
sick of these small fixups, and i would prefer just to fix documentation.

Kind regards,
