Is there desire to support things like std::time::Instant::now() etc. on wasm32-unknown-unknown? I tried to use it recently, but it seems to be behind the wasm_syscall feature flag, which is not enabled by default.
But it makes porting whole applications hard. Hardly any useful rust library or binary does not use any syscalls. I tried to port the littlewing chess engine for example. While pure chess calculations do not need syscalls, the engine needs a source of time to know when to stop searching for the next move. How should one approach porting such applications to wasm?
