Hi.
Thank you guys for your great project.
I am trying wasm32-unknown-unknown and got an error(panic) in std::time::SystemTime::now().
Here is a reproduction code.
#[no_mangle]
pub fn test() -> u32 {
use std::time;
let now = time::SystemTime::now();
return 1;
}<html lang="en">
<head>
<meta charset="utf-8">
<script>
fetch('wasm_time.wasm')
.then((response) => response.arrayBuffer())
.then((bytes) => WebAssembly.instantiate(bytes, {}))
.then((results) => {
const instance = results.instance;
console.log(instance.exports.test());
});
</script>
</head>

My environment is,
OS : macOS 10.13.3
Rust: rustc 1.26.0-nightly (322d7f7 2018-02-25)
Chrome: 64.0.3282.167
Sorry, I have no idea to confirm the version of wasm32-unknown-unknown.
Cheers.
