Worked on enhancing observability and code quality in the OpenCTI-Platform/client-python repository by addressing a logging issue related to timestamp formatting. Focused on Python logging and datetime handling, the developer replaced the deprecated use of datetime.utcnow() with datetime.now(tz=timezone.utc) in the logger’s formatter. This change ensured that all log entries now use ISO 8601, timezone-aware UTC timestamps, improving reliability and traceability across distributed systems. By eliminating naive datetime objects, the update minimized potential confusion in log analysis. The work demonstrated attention to detail in Python and logging best practices, with a targeted bug fix rather than new feature development.
