DST disrupting rsync twice a year
I'm facing `rsync` full syncs every once upon a time, I think it's because [DST][0], notice an hour of difference:

```
$ ls -l tier2/VIDEO-2020-06-17-15-10-27.mp4 /Volumes/KINSTON2/dat/laptop_kinstones/tier2/VIDEO-2020-06-17-15-10-27.mp4 
-rwxrwxrwx  1 ******  staff  3992777 Jun 18 09:57 /Volumes/KINSTON2/dat/laptop_kinstones/tier2/VIDEO-2020-06-17-15-10-27.mp4
-rw-r--r--@ 1 ******  staff  3992777 Jun 18 08:57 tier2/VIDEO-2020-06-17-15-10-27.mp4
```

Used options are:

```
$ rsync \
        --itemize-changes \  # just learned about this, helped me diagnostic
        --progress \  # most often not
        --recursive \
        --no-owner --no-group \  # because backing up towards MSDOS persistence
        --no-perms \  # same as above?
        --times \
        --delete \  # because backing up the left side
        --modify-window=3 \  # because backing up towards MSDOS persistence
        --verbose \  # because craving for feedback
        --dry-run \  # unless not quite
        tier2/ \  # src
        /Volumes/KINSTON2/dat/laptop_kinstones/tier2/  # dst
```

thx in advance (✿◠‿◠)
