Date time chronology calendar JSR-310 capabilities within rust

[omac777]

I understand JSR-310 was mentioned earlier. I understand others have mentioned this as issue on github, but why has the issue been closed when I haven't seen the capabilities as being implemented yet? If they have been implemented, please indicate where they are.

Thank you

Also, when I examined the new nom rust parser, it highlighted an iso datetime parser however without all the other JSR-310 capabilities which lead me to bring up this issue again.
There was no validation of the date time, just parsing. Looking for a date time validator, I found none within rust sufficient to address all the JSR-310.

Thank you for listening.

This is better suited as functionality for an external crate such as chrono. Adding big components like this to the standard library also needs to go through the RFC process, so closing in favor of that.
