Call later

call_at

Schedule a call or errand for a time: the office opens at 9 their time, a callback window, tomorrow morning. Same fields as errand/call plus run_at. Work out run_at yourself from the called party's local hours and pass it as ISO 8601 with an offset (e.g. 2026-11-09T09:05:00-07:00). Spends credits when it runs.
