Could you provide the code where this happens?

[ericCHensssssssss]

// 使用示例
@WasmExport
fun myTest() {

val now = Clock.System.now()
println("the time is"+now)

}

This code will produce the error，i run wasm at micro-wasm-runtime

Sorry, I couldn't reproduce your issue. When I run the code you provided in a Wasm/WASI test, the test passes with no problems. I don't know how to use "micro-wasm-runtime" to run Wasm programs. If you provide a self-contrained step-by-step instruction, I could look into it, but otherwise, I'd suspect that it's the runtime's fault: how come this code runs just fine in the browser?
