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.
