Panic on wasm: time not implemented on this platform

[andylokandy]

I gave it a spin and it seems to fail at runtime: time not implemented on this platform (on WASM runtime).

All I did so far it to add minitrace with features = ["enable"] and did the following at startup:

  let collector = LocalCollector::start();
  let result = run_flow(req, env).await;
  let local_spans = collector.collect();
  let parent_context = SpanContext::random();
  let span_records = local_spans.to_span_records(parent_context); // ❗ 

I'm pretty sure this originates in to_span_records, because without calling it, it seems to work fine. I printed local_spans and it seems to correctly contain the spans 🎉

It'll be hard to get timing done without a wall clock timer... Do you have any idea? @dotansimha

what about https://lib.rs/crates/web-time? @andylokandy

Seems good. Would you like to create a PR for adding web-time to minstant? SystemTime is only used in https://docs.rs/minstant/latest/minstant/struct.Anchor.html#method.new
