People keep tripping over the old copyrights and copy-pasting them to new files. Search and replace "Cloudius Systems" with "ScyllaDB". Message-Id: <1460013664-25966-1-git-send-email-penberg@scylladb.com>
Replace db_clock::now_in_usec() and db_clock::now() * 1000 accesses where the intent is to create a new auto-generate cell timestamp with a call to new_timestamp(). Now the knowledge of how to create timestamps is in a single place.
Avoid include hell for new code.
