(a)proceedings for an offence under that section may be brought within a period of six months from the date on which evidence sufficient in the opinion of the prosecutor to warrant the proceedings came to his knowledge, but
(b)no such proceedings shall be brought by virtue of this section more than three years after the commission of the offence.
(2)For the purposes of subsection (1) above a certificate signed by or on behalf of the prosecutor and stating the date on which evidence such as is mentioned in that subsection came to his knowledge, shall be conclusive evidence of that fact; and a certificate purporting to be so signed shall be deemed to be so signed unless the contrary is proved.
