Subject: [PATCH] Initialize start time for server (#2220)

* Initialize start time for server

By initializing start_time_ for server, I hope to measure the time taken to process a request at the end maybe in the set_logger callback and print it.

I only see current usage in client with server retaining the inital min value

* Add test to verify start time is initialized

* Address review comments

* run clang format
