Responsible-Changed-Why:
I am working on a solution for this problem (which is missing
overflow, and lots more, checking in parsedate() - date is
simply one of parsedate()'s clients).

 Module Name:	src
 Committed By:	kre
 Date:		Fri Oct 30 22:03:11 UTC 2020

 Modified Files:
 	src/lib/libutil: parsedate.y

 Log Message:
 PR lib/46542

 Add checks to detect overflow, and also detect other invalid
 (out of range) inputs for parsedate().

 There could be more, and some of what is being added is not
 perfect, but many calculation overflows will be detected now
 (and cause an error return) and some of the most bizarre
 inputs that were previously accepted no longer will be.

 I think so, but it wasn't my PR.
