I get the following when trying to install cap-primitives on win10 x64 on the latest stable rust.

error[E0046]: not all trait items implemented, missing: `change_time`

I've now released cap-std 2.0.2, which I expect fixes this for 2.x users. From the error message, it appear you're using cap-std 1.x. I have started to look into backporting the fixes to 1.x, but it's non-trivial because of cap-std 1.x's MSRV of 1.56.

let me know when 1.x fix happens and I will validate. thank you much appreciated.

[sunfishcode]

Backporting the fix to cap-std 1.x is too complex due to the MSRV of 1.56. I think it's best if users needing support for newer Rust versions to update to newer cap-std versions.

I'm not sure the maintainer is interested. I'm not sure if I know enough. I respect any decision you make in terms of version support.

If you can point me in general directions I might look, this has been one that I've tried a couple times.

Thanks for following back. This ticket can close if you'd like.
