I don’t agree.
Paragraph 10(4) modifies section 136(1) of the 1995 Act so as to provide that the time limit for the commencement of proceedings for any statutory offence triable only summarily, unless the enactment fixes a different time limit, is temporarily increased from 6 months to 12 months.

If you follow the link to s136 (1) this is what it says:
Time limit for certain offences.
(1)Proceedings under this Part of this Act in respect of any offence to which this section applies shall be commenced—
(a)within [F1six months] [F112 months] after the contravention occurred;
(b)in the case of a continuous contravention, within [F1six months] [F112 months] after the last date of such contravention,
and it shall be competent in a prosecution of a contravention mentioned in paragraph (b) above to include the entire period during which the contravention occurred.
(2)This section applies to any offence triable only summarily and consisting of the contravention of any enactment, unless the enactment fixes a different time limit.
(3)For the purposes of this section proceedings shall be deemed to be commenced on the date on which a warrant to apprehend or to cite the accused is granted, if the warrant is executed without undue delay.

So it is clear that the 12 month period relates to the citation being issued, not the court appearance, which can be later.
