Log filenames used UTC time while cron runs in local time, causing different runs to generate the same filename (e.g. 04:00 local and 06:00 local both mapped to 04:00 UTC). Use local time for log filenames to ensure each run gets a unique file. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
