First PR to replace pytz with zoneinfo for UTC handling across codebase. This PR migrates all UTC timezone handling from pytz to Python’s standard library zoneinfo. The pytz library is now deprecated, and its documentation recommends using zoneinfo for all new code. This update modernizes our codebase, removes legacy pytz usage, and ensures compatibility with current best practices for timezone management in Python 3.9+. No functional changes to timezone logic - just a direct replacement for UTC handling. https://github.com/openedx/edx-platform/issues/33980
Status: Maintenance Responsibilities ================ The ``user_authn`` app contains user authentication related features such as login, registration, and credential management. Direction: Extract ================== Ideally this would be in its own service, but at this point, LMS is the home of all authentication related features. At this time, these features are still plugged into Studio. Future clean-up in Studio is intended to make this an LMS only feature. Glossary ======== More Documentation ==================
