This skill provides the definitive guide for managing time in OpenClaw. It solves the "I missed my reminder" problem by enforcing a strict separation between casual checks (heartbeat) and hard schedules (cron).

| System | Behavior | Best For | Risk |

| Heartbeat | "I'll check in when I can" (e.g., every 30-60m) | Email checks, casual news summaries, low-priority polling. | Drift: A "remind me in 10m" task will fail if the heartbeat is 30m. | | Cron | "I will run at exactly X time" | Reminders ("in 5 mins"), daily reports, system maintenance. | Clutter: Creates one-off jobs that need cleanup. |
