croniter 6.0.0 has two unbounded memory leaks ([#182](pallets-eco/croniter#182), [#195](pallets-eco/croniter#195)) that are fixed in main but unreleased — and the project was declared unmaintained by Pallets Community Ecosystem in March 2025, so no release is coming. It also drags in pytz and python-dateutil as transitive deps. cronsim is actively maintained (~280 lines, zero deps, Python 3.10+), used in production by Healthchecks.io, and handles DST via zoneinfo natively. One gap: cronsim doesn't support Vixie keywords (@daily, @hourly, etc.), so we add a small mapping dict that expands them before passing to CronSim. Also extracted `Cron.next_time()` so tests mock at docket's abstraction level rather than the library's internals, and added contract tests that exercise the real cronsim integration (sequential times, timezone handling, keyword validity).
