In many places we measure the time that something takes to complete, for example https://github.com/metabrainz/listenbrainz-server/blob/7a9db9b435f0b685972484678f917b78dccabb23/listenbrainz_spark/hdfs/__init__.py
when counting elapsed time we should use time.monotonic() instead, as it doesn't suffer from effects such as the time shifting due to the system clock changing.
