The timeframe covered from one page carried but, let me provide you with the length of time between each page. Begging at page 554 we have 5 years, 1 year, 4 years, 2, year, 4 years,10 years, 2, years, 1 year, 8 years, 4 years, and then 4 years from page 563-564. And often times these years take place from one sentence to another.
It is not until the last 4-5 pages that you are brought into detail of Mormon and his account of the last battles that are being prepared for between the Nephites and the Lamanites. Over the course of the rest of the reading however you are just given a sample of information as to why there is conflict between the two parties. Without the clear mention of the time laps it would be very easy to combine all the events into a much shorter period such as a few months or even just a year or two. You could easily miss the fact this was a slow process of war and contention taking 64 years of time.
Impressive amongst the time laps that quickly occurs is the flow and continuity with which the author has complied the information.
