Clock (Brave 5.13.9 API)

```
public interface Clock
```
Epoch microseconds used for Span.start(long), Span.finish(long) and Span.annotate(long, String).
This should use the most precise value possible. For example, gettimeofday or multiplying System.currentTimeMillis() by 1000.
See Instrumenting a service for more.
Note: This type is safe to implement as a lambda, or use as a method reference as it is effectively a FunctionalInterface. It isn't annotated as such because the project has a minimum Java language level 6.
