Good challenge to get the dates in the same format as the output.

Very nice challenge @Qiu , thank you!  I've submitted a WC idea with similar concepts.  Hopefully we will see it published eventually.

I think there's a minor sort inaccuracy in the output included in the Start file that the reasons appear in the wrong order in which they occur but it doesn't affect the results in a noticeable way unless you attempt to reconcile all the values to the ones in the output file included.
