I don't believe that is true [anymore]:

$ rsync --help
rsync  version 3.0.9  protocol version 30

 -c, --checksum              skip based on checksum, not mod-time & size
 ...
 -I, --ignore-times          don't skip files that match in size and mod-time
     --size-only             skip files that match in size
     --modify-window=NUM     compare mod-times with reduced accuracy
