coreutils date: fix %Z specifier does not print TZ abbr

fixes issue https://github.com/uutils/coreutils/issues/3756 for date util

description: chrono crate ignores %Z specifier. only prints timezone offset. added crates chrono-tz and iana_time_zone to calculate the timezone abbreviation and replace %Z specifier with the the abbreviation.

Cool! Having two additional crates is a bit unfortunate, but if that is the best solution it's alright. I think the CI is failing because you didn't push changes to Cargo.lock.

Yeah! chrono v0.5 supposed to have a fix for this. will revisit this once v0.5 is released. https://github.com/chronotope/chrono/issues/970.

BTW, I have pushed the cargo.lock changes.

Still CI is failing. I have enabled Github Actions in my repo to run these tests myself. I will come back once all tests are passed.

Yeah! chrono v0.5 supposed to have a fix for this.

While you're fixing the tests, it might be nice to add a comment with this info to the code.
