Are you reading that as "atime gets updated every 24 hrs"? If so you are missing "if needed". I.e. if the file's data blocks have been read.
Checking time-stamps and sizes are not operations that cause atime updates. Those are inode operations, not data reads.
That I got. I was concerned with the case where rsync does a checksum to verify that the file's contents didn't change without changing the timestamp.
