Can trace 's timestamp precision reach microsecond level？

[bigbanglwb]

I tried to research the overhead of communication in microservice with Skywalking. However, the timestamp precision is millisecond level as the figure show and not able to analyze the overhead. I want to know if there is some configuration can make Skywalking trace's timestamp precision reach microsecond level?

I know jaeger can achieve microsecond level. It gives millisecond level timestamp of start time and microsecond level duration.

No, there isn't. Because we don't think it is reasonable to use an APM tool to diagnose a perf issue less than 1 ms.
There is no case for that. Creating a span would take nearly 0.01 - 0.1 ms even ignoring the GC and serialization(in report) cost.
This is never about what unit we provide.
