For example, the reference processor uses os::javaTimeNanos because it interacts with java.lang.ref.SoftReference.clock. Most other places in the JVM uses os::elapsed_counter().

Both uses a 'java type', jlong.
For logging and logic for yielding we want a humanly understand unit that is absolute.
Since things goes pretty fast nowadays nanseconds seems reasonable.
Instead of to converting the elapsed_counter to nanos, it's much simpler to just get the nanos.
But yes it would preferably with a os::timeNanos().
