Production Tips

Timezone Considerations

Cron expressions run in UTC by default. ClawTick lets you specify IANA timezones per job (e.g., America/New_York, Europe/London).

Monitoring & Alerts

Always monitor scheduled jobs for failures. ClawTick provides built-in execution history and failure alerts so you know immediately when something breaks.

Idempotency

Design jobs to be idempotent (safe to run multiple times). This prevents issues if a trigger fires twice due to network retries or scheduler edge cases.
