Incorrect timestamp for httpstrace

[kivens]

For 2.0.2 version
I found the incorrect timestamp about httpstrace from ui
the endpoint is return like this
{timestamp:{nano:672000000,epochSecond:1536055350},.....}
but the ui show
2018/09/04 00:00:00.000

Your output should contain timestamps formatted this way "timestamp":"2018-09-04T13:07:18.226Z"

So I guess you've customized your object mapper. For SBA we depend on the default configuration.
