Panic when with target wasm32-wasi

[sonhal]

Hi i am using the https://github.com/jedisct1/rust-jwt-simple library for my Envoy wasm filter. I am using wasm32-wasi as a target. Seems like this library panics when getting the current time with:

[source/extensions/common/wasm/context.cc:1180] wasm log: panicked at 'Clock not available: Error { code: 58, name: "NOTSUP", message: "Not supported, or operation not supported on socket." }', /Users/sondre/.cargo/registry/src/github.com-1ecc6299db9ec823/coarsetime-0.1.18/src/instant.rs:164:67

Are you aware of this issue with the wasm32-wasi target?

Checked, and it works with CLOCKID_REALTIME, since the tokens usually are received from over the network, is it really necessary with a monotonic clock?

Looks like this is something that the runtime doesn't implement.

What WebAssembly runtime is it?

Sorry @jedisct1, it was indeed the runtime: proxy-wasm/proxy-wasm-rust-sdk#103

Your a god damn champ @jedisct1 🎉 I think you just saved a big part of my thesis work :)
