When parsing with "tt", it requires using "hh"

[pbiggar]

According to stackoverflow (and this matches my tests locally), you can't call DateTime.ParseExact with both HH and tt. Instead you must use hh.

https://stackoverflow.com/questions/2596969/why-can-t-datetime-parseexact-parse-the-am-pm-in-4-4-2010-42000-pm-using

This would be good to mention in the docs.
