In many fictional settings, there exist multiple timelines during which the stories take place. Although it is merely conjecture, I believe that the possibility of multiple timelines in the Cosmere may be considerable. Such a multiple-timeline system would explain possible discrepancies in the timeline, and would likely arise from Investiture-powered time-travel techniques. It may be simply idle conjecture, but could this be justified by any existing evidence of temporal weirdness in the Cosmere?
