  The possibility to compute nucleon electromagnetic form factors in the
time-like region by analytic continuation of their space-like expressions has
been explored in the framework of the Skyrme model. We have developed a
procedure to solve analytically Fourier transforms of the nucleon
electromagnetic current and hence to obtain form factors defined in all
kinematical regions and fulfilling the first-principles requirements. The
results are discussed and compared to data, both in space-like and time-like
region.
