What are the time units used by the artillery-engine-grpc reports

[fage88]

I have an API I have implemented in both REST and gRPC.
I am trying to load test them to prove which is more performant.
I am using artillery and the grpc plugin to accomplish this.
The output I get for my gRPC load test is

Summary report @ 13:40:48(-0400) 2021-10-18
  Scenarios launched:  300

  engine.grpc.response_time:

  engine.grpc.responses.total: 4756
  engine.grpc.responses.success: 4752
  engine.grpc.codes.0: 4752
  engine.grpc.responses.error: 4
  engine.grpc.codes.6: 4

But I am not 100% sure what time unit the engine.grpc.response_time value is in. My guess is it is in nano seconds but I am not sure.

Can anyone let me know what this value is in or if there is a way in my config where I define the grpc engine can I set the time units?

@fage88 it looks like it's milliseconds: https://github.com/kenju/artillery-engine-grpc/blob/master/index.js#L134

Thank you @hassy
