format_time() converts an aware datetime to a Unix timestamp, then reconstructs it using the host's local timezone. This changes the displayed clock time and drops its UTC offset. The same input can therefore render differently on different hosts.

Pass the input datetime's timezone to fromtimestamp(), preserving the represented instant, its timezone and the existing precision truncation. Naive inputs continue to use local time. Tests cover UTC, positive and negative offsets, plus the naive behavior; add an aware-datetime doctest.

Three new timezone regressions fail before the fix and the naive control passes. Full Python 3.10 and 3.12 suites: 373 passed, 5 optional timezone-data skips, 100% branch/statement coverage. Whole-project mypy, basedpyright and Pyrefly report no errors. Ruff lint and formatting of changed files, plus git diff --check, pass. No matching open issue or PR found.
