2006 New York Code - When Ordinance Shall Take Effect.

 
    §  133.  When  ordinance  shall take effect. Every ordinance and every
  amendment to an ordinance hereafter adopted  or  approved  by  the  town
  board  of a town to which the provisions of this article are applicable,
  shall be entered in its minutes except that it shall not be necessary to
  enter in its minutes any map adopted or approved in  connection  with  a
  zoning  ordinance or amendment. The ordinance or amendment, or a summary
  or abstract thereof, shall be published in the official newspaper of the
  town or, if there is none, in a newspaper designated by the  town  board
  having  general circulation in the town, once, and the affidavit of such
  publication shall be filed  with  the  town  clerk.  Such  ordinance  or
  amendment  shall  take  effect ten days after such publication; but such
  ordinance or amendment shall take effect from the date of its service as
  against a person served personally with a copy thereof, certified by the
  town clerk under the corporate seal of the town; and showing the date of
  its passage  and  entry  in  the  minutes.  No  ordinance  or  amendment
  previously  adopted or approved by any town board of a town to which the
  provisions of this article are applicable shall be void for  failure  of
  posting and/or filing affidavits of posting.
