The SoapUI request log appears to have incorrect time stamps

I am trying to do some performance testing between two servers. I am seeing some weird timings occur on one and when I started digging into it I found that the time taken that is being reported by SoapUI does not match our application logs on our servers.

I've attached a screenshot of what is reported in the SoapUI request log versus the time stamps I got off our server of when the request was sent and the response received. The difference is 15ms

Request timestamp from our server is 2015-02-16 19:51:16,689

Response timestamp from our server is 2015-02-16 19:51:16,693

In the SoapUI request log I see

• Mon Feb 16 19:51:19 UTC 2015:INFO:Got response for [***********************************************************************] in 19ms (442 bytes)
