Restore timestamps on C++ logs without glog (#121384)
It looks like it was commented out because the original implementation was not sufficiently portable. I had to do some rewrites to the innards to make it no portable. No Windows nanoseconds support because I'm lazy.
I tested by running `build/bin/TCPStoreTest` and observing the log messages there. I am actually not sure how to look at the log messages from Python though.
