The Provincial Archives has a Xeroxed copy of records called Sackville, New Brunswick - Births, Marriages and Deaths - From the First Settlement to the Early 1800's. (As transcribed from a photostatic copy of the Sackville Town Book in the New Brunswick Museum, St. John, N.B.)  This implies that it is a record made of these events as they occured. In some cases this may be so, but in others I feel that the events were recorded as a type of census, when the family moved into the area, or when the book was begun, etc. Charles Dixon arrived from Yorkshire, England in 1772 yet four of his children born pre that date are listed. I am therefore inclined to think of this record being similar to the Town Books of the New England States that took mini-census of the population in their districts, in which you often find families that moved a lot recorded in several.(remarks from Cleadie Barnett).
