I posit that the earth’s days lengthened during the time of Peleg, as the continents quickly divided. This seems to be when the days changed.To Eber were born two sons: the name of the one was Peleg, for in his days the earth was divided, and his brother’s name was Joktan. Genesis 10:25 (ESV)

FOR IN HIS DAYS THE EARTH WAS DIVIDED CLASSIC JEWISH SOURCES FOR A PHYSICAL DIVISION OF THE EARTH
(Dr. Joshua Backon teaches at the Hebrew University Faculty of Medicine and is the ProgramAdministrator of the college program of the Jewish Bible Association)
Genesis 10 transmits the genealogical list of descendants of Noah. When it comes to the generation of Peleg, about 350 years after the Flood, the Bible reports, For in his days the earth was divided (Gen. 10:25; I Chron. 1:19). Owing to the juxtaposition in Genesis of this section with the following sectionon the Tower of Babel, Rashi in his commentary explains the term "niflega [divided]" as referring to the "dispersal" of the people around the world. Yet the actual term niflega literally means "split" or "cleaved" (see: Job 38:25; Isa. 30:25).
On the other hand, a far different perspective on the meaning of niflega has been offered: Many non-Jewish "Creationist" websites relate niflega to catastrophic plate tectonics (see below); a cataclysmic event that literally severed what had been a single land mass into separate continents.
The Tosafot Yom Tov, a commentary on the Mishna, indicates that if there [is] no difference with regard to Jewish law between the explanation of a verse as given in the Talmud and one's own interpretation, then it is permissible to interpret biblical text according to one's understanding (Mishna Nazir 5:5). I was curious to learn whether classic Jewish sources had ever dealt with this phenomenon. I now suggest that there is support in Jewish tradition for interpreting niflega as a physical division of the earth. This view is remarkable, for modern scientific evidence for this has been discovered only within the past 35 years.
CATASTROPHIC PLATE TECTONICS
Catastrophic plate tectonics, the idea that the continents have drifted apart, was first suggested in 1859 after a geologist noticed a jigsaw fit between the western coastline of Africa and the eastern coastline of South America. The theory that these continents had once been joined but had split and moved apart was recognized by the scientific community after the findings of the German meteorologist Alfred Wegener were published in 1915. Most scientists at that time felt this phenomenon took place over millions of years. However, many physical observations have been found to be incompatible with the idea of slow-and-gradual plate tectonics. A recent theory of catastrophic plate tectonics with extremely rapid formation of new ocean crust and magnetic reversals has been proposed and demonstrated in the past three decades.
As indicated above, catastrophic plate tectonics posits that massive flooding would have occurred as a result of the melting of hot mantle rock on the ocean floor. There are many classic Jewish sources for a massive flood during the time of Peleg....
My opinion: When will the days of the year change again? We have learned from the great 2011 Japanese Earthquake that our rotation speed increased afterward. I believe that we will see a 360 day year by 2015 or 2022. I have more proof now (please ignore the millions of years lunacy).

Research reveals Earth's core affects length of day
Research reveals Earth's core affects length of day
Liverpool, UK (SPX) Jul 12, 2013Research at the University of Liverpool has found that variations in the length of day over periods of between one and 10 years are caused by processes in the Earth's core.
The Earth rotates once per day, but the length of this day varies. A year, 300 million years ago, lasted about 450 days and a day would last about 21 hours. As a result of the slowing down of the Earth's rotation the length of day has increased.The rotation of the earth on its axis, however, is affected by a number of other factors - for example, the force of the wind against mountain ranges changes the length of the day by plus or minus a millisecond over a period of a year.
Professor Richard Holme, from the School of Environmental Sciences, studied the variations and fluctuations in the length of day over a one to 10 year period between 1962 and 2012. The study took account of the effects on the Earth's rotation of atmospheric and oceanic processes to produce a model of the variations in the length of day on time scales longer than a year.Professor Holme said: "The model shows well-known variations on decadal time scales, but importantly resolves changes over periods between one and 10 years. Previously these changes were poorly characterised; the study shows they can be explained by just two key signals, a steady 5.9 year oscillation and episodic jumps which occur at the same time as abrupt changes in the Earth's magnetic field, generated in the Earth's core.
He added: "This study changes fundamentally our understanding of short-period dynamics of the Earth's fluid core. It leads us to conclude that the Earth's lower mantle, which sits above the Earth's outer core, is a poor conductor of electricity giving us new insight into the chemistry and mineralogy of the Earth's deep interior."
