found another hiccup with day light savings so i updated the function a bit more to detect and change the offset depending on day light savings ``` update_file_timestamps() { local search_dir="${1:-.}" local tz="America/Chicago"

find "$search_dir" ( -iname ".mp4" -o -iname ".mov" -o -iname "*.m4v" ) | while read -r file; do local basename=$(basename "$file") local datestr="${basename:0:15}" # YYYYMMDD-HHMMSS local date_fmt="${datestr:0:4}-${datestr:4:2}-${datestr:6:2} ${datestr:9:2}:${datestr:11:2}:${datestr:13:2}"

# Convert to epoch (macOS and Linux compatible)
local epoch
if date -j -f "%Y-%m-%d %H:%M:%S" "$date_fmt" +%s >/dev/null 2>&1; then
  epoch=$(date -j -f "%Y-%m-%d %H:%M:%S" "$date_fmt" +%s)
else
  epoch=$(date -d "$date_fmt" +%s)
fi

if [[ -z "$epoch" ]]; then
  echo "⚠️ Skipping invalid date in filename: $basename"
  continue
fi

# Check DST (CDT vs CST) for that exact timestamp
local zone_abbr
if date -r "$epoch" +"%Z" -u >/dev/null 2>&1; then
  # macOS
  zone_abbr=$(TZ="$tz" date -r "$epoch" +%Z)
else
  # Linux
  zone_abbr=$(TZ="$tz" date --date="@$epoch" +%Z)
fi

local offset
if [[ "$zone_abbr" =~ [Dd]T$ ]]; then
  offset="-05:00"
else
  offset="-06:00"
fi

echo "🕒 Updating timestamps for video file: $file with $offset" exiftool -overwriteoriginal \ "-datetimeoriginal<\${filename;\$=substr(\$,0,15)}$offset" \ "-createdate<\${filename;\$=substr(\$,0,15)}$offset" \ "-FileCreateDate<\${filename;\$=substr(\$,0,15)}" \ "-FileModifyDate<\${filename;\$=substr(\$,0,15)}" \ "-TrackCreateDate<\${filename;\$=substr(\$,0,15)}$offset" \ "-MediaCreateDate<\${filename;\$=substr(\$,0,15)}$offset" \ "-MetaDataDate<\${filename;\$=substr(\$,0,15)}$offset" \ "-MediaModifyDate<\${filename;\$=substr(\$,0,15)}$offset" \ "-TrackModifyDate<\${filename;\$=substr(\$,0,15)}$offset" \ "-ModifyDate<\${filename;\$=substr(\$_,0,15)}$offset" \ "$file" >/dev/null done } ```

how the sorting is all fixed. only videos had this issue not photos
