Compilation error[E0277]: the trait bound `Tz: Copy` is not satisfied

I get the following error trying to compile the crate:

I believe this is caused by one of the latest chrono versions, that included changes and deprecations. I am using chrono 0.4.37 and chrono-tz 0.8.6 .

Just ran into this myself.

It would be awesome if this could be fixed upstream. @stevedonovan could you take a look at this and eventually publish a new release :)?

I fixed the problem in https://github.com/stevedonovan/chrono-english/pull/30/commits/8e07035d56c89a437f3cb237f5ca1f39a7d43549

You're a lifesaver mate. This is the only library that can do what I want to do (human input parsing for a discord bot to set reminders) other than going overkill and using some LLM or other such BS. I will probably tell cargo to use your PR until there is an official release.

[Nukesor]

You're welcome :). We definitely need this in a release though^^ This currently prevents dependant libraries from upgrading chrono. One cannot release crates that point to git repositories, all dependencies need to be published on crates.io :sweat:

[Nukesor]

I fixed this by switching to the drop-in replacement https://github.com/conradludgate/interim

It seems well-maintained, properly tested and has the exact same API surface.
