How to get a timestamp (or tick count) in a WASM module?

Is there a method to get a timestamp or tick-count in a WASM module (standalone) to millisecond resolution?
I get a runtime error when trying to use clock():

WASM: Error ERR_ILLEGAL_C_IMPORT: env:clock is not a whitelisted C import, nor a valid webassembly import.

and GetTickCount() doesn't seem to be available either.

Thanks in Advance.

Try this:

auto now_miliseconds = std::chrono::duration_cast<std::chrono::milliseconds>(std::chrono::system_clock::now().time_since_epoch()).count();
