Matomo's cdt parameter expects timestamps in UTC timezone, but we were sending local timezone timestamps (e.g., CET) without conversion. This caused backfill visits to appear at incorrect times in Matomo. Changes: - Add format_cdt() helper that converts timezone-aware datetimes to UTC - Replace all strftime calls for cdt param with format_cdt() - Add test_format_cdt_converts_to_utc() to verify conversion Example: - Before: 14:30 CET sent as '2025-12-01 14:30:00' (Matomo interprets as UTC) - After: 14:30 CET sent as '2025-12-01 13:30:00' (correct UTC equivalent) Fixes P-032 backfill not sending data to correct dates.
Standalone script to verify backfill functionality against a local Matomo: - Sends test visits with historical timestamps (UTC-converted) - Validates Matomo connectivity and token_auth - Reports success/failure by date - Provides verification steps for manual inspection Usage: MATOMO_TOKEN_AUTH='token' python3 test_backfill_local.py
