A timeline for Alma(1) and Alma(2)

The following is a rough timeline for the lives of Alma the Elder and Alma the Younger. Some of the dates are approximations based on other events, some are guesses from clues in the Book of Mormon. I'd love to hear what people think.

Without further ado, the timeline:
