Three things: 1) On boot, the hardware clock is copied to the system clock. The adjtime file says how much time has to be added/removed to compensate for drift. 2) When chrony is not running, systemd-timedated runs periodically to adjust the hardware clock for drift (AFAIK, not sure that is the job that timedated does). 3) When chrony is running, chrony adjusts the hardware clock for drift.
