also can do annotation with the date:

set -e

mkdir snapshots-copy
cd timelapse
count=0
for f in *.jpg ; do
  printf -v counts "%06d" $count
  out=../snapshots-copy/$counts.jpg
  day=${f:0:10}
  time=${f:11:5}
  txt="$day    $time"
  convert $f \
    -font ../src/Game/MinimalPixels.ttf \
    -pointsize 100 \
    -gravity SouthWest \
    -fill '#000' -annotate +24+14 "$txt" \
    -fill '#000' -annotate +16+6 "$txt" \
    -fill '#000' -annotate +24+6 "$txt" \
    -fill '#000' -annotate +16+14 "$txt" \
    -fill '#fff' -annotate +20+10 "$txt" \
    $out
  count=`expr $count + 1`
done
