On UNIX, time.time() currently uses clock_gettime(), but _PyTime_gettimeofday() doesn't becauce pytime.c lacks a dependency on the librt module (needed on some platforms).

Attached patch adds the dependency if needed and modify _PyTime_gettimeofday() to use clock_gettime() if available.

The patch alone is not very useful. I wrote it to prepare the work for the issue #22043 (use a monotonic clock in Python modules written in C).

With the patch, Python depends on the librt on Solaris and on Linux with glibc older than 2.17 (clock_gettime is now available directly in the libc since glibc 2.17).
