A RTC is a hardware clock. "RTC in local TZ: yes" only indicates, that the RTC would have been in local TZ. The alternative is UTC. Please check the warning for more information. If you want a bit of time improvement without buying a RTC (and configuring it...), you can use systemd-timesyncd. It basically writes the current time periodically to a file. It also writes the time very late on shutdown to that file and gets the time from that file at startup early.
