X Title: gh-141431: interpret ZIP timestamps as UTC by VanshAgarwal24036 · Pull Request #143953 · python/cpython

Description: ZIP (DOS) timestamps do not include timezone information, but CPython currently interprets them as local time via time.mktime(). This can cause .pyc files to be incorrectly marked as stale when a zipapp is created and run in different timezones. This change uses calendar.timegm() so ZIP source timestamps are interpreted with UTC semantics, matching .pyc timestamp handling. Fixes gh-141431
