User-reported issue: server logs were timestamped in UTC ("05:36:20"
when local was ~01:36 EDT), and the PDF report's "Created" footer
similarly showed raw UTC. Inconsistent with the modal which already
converts to browser local via toLocaleString.
Solution: standard Linux TZ env var. Set once in the container, and:
- Python's datetime.now() uses local
- Logging module's timestamps use local
- matplotlib renderers + report_pdf formatters use local
- astimezone() conversions resolve to the configured TZ
DB columns stay UTC (created_at uses SQLite's strftime('%Y-...Z', 'now')
which is always UTC, regardless of TZ env var — proper "store UTC,
display local" pattern).
Changes:
- Dockerfile: install tzdata (python:3.11-slim omits the timezone
database), set default TZ=America/New_York
- sfm/report_pdf.py: _fmt_iso_to_bw and _split_iso_to_date_time now
convert UTC inputs (Z-suffixed) to local via astimezone(); naïve
inputs (BW recorded-at, already unit-local) returned as-is.
New _to_display_local helper centralizes the logic.
- "Created" line in the PDF page footer now uses the converted
timestamp.
Override per-deployment via the TZ env var in docker-compose
(separate commit on terra-view side).
