Release 9.5 introduces 9 new rules for C# and VB.NET developers, providing guidelines and best practices for handling date and time operations within their applications.
These rules cover a wide range of topics, including time zone conventions, common pitfalls, date parsing and formatting, time arithmetic, and more.
This release includes also one additional security rule and introduces fixes for false negatives and false positives.
Thanks to @Corniel for his contribution by implementing a new codefix for S6610 (#7517) and fixing a FP in S6354 (#7504).
