Clockrift
Map recurring jobs across local time, duration, frequency, DST transition windows, overlap, missed-run behavior, and ownership.
Focused field tools
State whether a job follows wall time, UTC, an interval, or an event.
Decide what happens when a local wall-clock time does not exist.
Decide whether repeated local times run once, twice, or by identity key.
Compare worst-case duration with cadence and concurrency controls.
Give every execution a stable business key and safe replay behavior.
Bound retry count, delay, jitter, deadline, and duplicate side effects.
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.
