[Bug] Parsing an string with %Z causes the library to panic

[DiegoMagdaleno]

I have the following Date string:

"2020-04-12 22:10 ACST"

And I do the following:

let datetime = chrono::DateTime::parse_from_str(date_str, "%Y-%m-%d %H:%M %Z").unwrap();

And I get a panic:

This doesn't happen in C with strftime()

Confirm, I run into the same issue.

I reopened the related issue https://github.com/chronotope/chrono/issues/38 because it is older and has some useful discussion. Closing this one as a duplicate.
