GPL source policy.

Hi,

There is a section from GPL:

    b) Accompany it with a written offer, valid for at least three
    years, to give any third party, for a charge no more than your
    cost of physically performing source distribution, a complete
    machine-readable copy of the corresponding source code, to be
    distributed under the terms of Sections 1 and 2 above on a medium
    customarily used for software interchange; or,


In this, the licence sait that `valid for at least three years', but I can't
understand what date the beginnings of `at least three years' starts
actually from. From the date when the vendor began to sell it, or when
buyers bought it, or else?
