For the libraries you listed, the benefits of using a native library are much larger, since they’re wrapping a well-known library that is known to be secure and fully-featured, or since the performance benefits are actually visible in any significant code snippet. But here, there is no Rust library to wrap, and I doubt the performance of a date-time library would have any effect on the performance of virtually all applications (maybe except for calendar apps).
