Igor Canadi b8d23cdcb8 Revert chrono use 
Summary:
For some reason, libstdc++ implements steady_clock::now() using syscall instead of VDSO optimized clock_gettime() when using glibc 2.16 and earlier. This leads to significant performance degradation for users with older glibcs. See bug reported here: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59177

We observed this behavior when testing mongo on AWS hosts. Facebook hosts are unaffected since we use glibc2.17 and 2.20.

Revert "Fix timing"
This reverts commit 965d9d50b8cbb413de5e834b5b83ddbb682d0f1d.
