Interestingly enough, Smith actually thinks to record the time for the journey when Nephi left Jerusalem but the inconsistency between this and Nephi fleeing from the Lamanites as quoted earlier is glaringly obvious:
1 Nephi 2 wrote:
6 And it came to pass that when he had traveled three days in the wilderness, he pitched his tent in a valley by the side of a river of water.
Another important journey documents the time spent traveling:
1 Nephi 16 wrote:
13 And it came to pass that we traveled for the space of four days, nearly a south-southeast direction, and we did pitch our tents again; and we did call the name of the place Shazer.
Then, Smith goes back to being inconsistent with his story as if his characters were so tired that they lost track of all sense of time:
1 Nephi 16 wrote:
15 And it came to pass that we did travel for the space of many days, slaying food by the way, with our bows and our arrows and our stones and our slings.
17 And after we had traveled for the space of many days, we did pitch our tents for the space of a time, that we might again rest ourselves and obtain food for our families.
33 And it came to pass that we did again take our journey, traveling nearly the same course as in the beginning; and after we had traveled for the space of many days we did pitch our tents again, that we might tarry for the space of a time.
Lo and behold, Smith seems to remind himself that he better be consistent with his story and keep better track of time lest his characters get lost:
Mosiah 7 wrote:
4 And now, they knew not the course they should travel in the wilderness to go up to the land of Lehi-Nephi; therefore they wandered many days in the wilderness, even forty days did they wander.
5 And when they had wandered forty days they came to a hill, which is north of the land of Shilom, and there they pitched their tents.
But back to inconsistency and a total loss of keeping track of time, even when lost in the wilderness:
Mosiah 8 wrote:
8 And they were lost in the wilderness for the space of many days, yet they were diligent, and found not the land of Zarahemla but returned to this land, having traveled in a land among many waters, having discovered a land which was covered with bones of men, and of beasts, and was also covered with ruins of buildings of every kind, having discovered a land which had been peopled with a people who were as numerous as the hosts of Israel.
Mosiah 9 wrote:
4 Nevertheless, after many days’ wandering in the wilderness we pitched our tents in the place where our brethren were slain, which was near to the land of our fathers.
Mosiah 22 wrote:
13 And after being many days in the wilderness they arrived in the land of Zarahemla, and joined Mosiah’s people, and became his subjects.
But back to being consistent and keeping track of time:
Mosiah 22 wrote:
16 And after they had pursued them two days, they could no longer follow their tracks; therefore they were lost in the wilderness.
Mosiah 23 wrote:
3 And they fled eight days’ journey into the wilderness.
Mosiah 24 wrote:
25 And after they had been in the wilderness twelve days they arrived in the land of Zarahemla; and king Mosiah did also receive them with joy.
Alma 8 wrote:
6 So that when he had finished his work at Melek he departed thence, and traveled three days’ journey on the north of the land of Melek; and he came to a city which was called Ammonihah.
Only to be inconsistent yet again:
Alma 17 wrote:
9 And it came to pass that they journeyed many days in the wilderness . . . .
Ether 9 wrote:
3 And the Lord warned Omer in a dream that he should depart out of the land; wherefore Omer departed out of the land with his family, and traveled many days, and came over and passed by the hill of Shim, and came over by the place where the Nephites were destroyed, and from thence eastward, and came to a place which was called Ablom, by the seashore, and there he pitched his tent, and also his sons and his daughters, and all his household, save it were Jared and his family.
And back to consistency:
Ether 14 wrote:
26 And it came to pass that Shiz did pursue Coriantumr eastward, even to the borders by the seashore, and there he gave battle unto Shiz for the space of three days.
Joseph Smith's record keeping in telling stories is an utter mess.
