Clockrift: Cron Simulator

Clockrift is a local recurring-job rehearsal tool for developers, operators, data teams, and automation owners who need to reason about time before a schedule fails. Screen recurring work against DST windows, duration, cadence, and the recovery semantics that schedulers often leave implicit. KEY FEATURES - 24-hour execution clock - DST risk scoring - Duration and frequency overlap model - Local-versus-UTC intent record - Idempotency and retry notes - Owner and status workflow - CSV schedule import - Portable review export - Local PDF and JSON export - No account, ads, analytics, tracking, IAP, or subscription Clockrift is a planning model, not a scheduler. Runtime behavior varies by cron implementation, operating system, orchestrator, timezone database, retry policy, clock source, and workload. Verify the deployed scheduler and test transition dates directly.
