Given the common element of time and date formatting strings as a domain specific language, there would be more benefit to leveraging one of several existing mechanisms to generate optimized formatters from application or library format strings. For example, the general purpose [JEP 430: String Template](https://openjdk.org/jeps/430)s could be used to compose the string and leverage its optimizations of formatting the components. Making improvements there either to performance or functionality would benefit more applications. ------------- PR Comment: https://git.openjdk.org/jdk/pull/15658#issuecomment-1726038572
