Rules
Writing a rule, combining several, and reading the statuses and warnings the editor gives you back.
- Reading the rule list The three rule statuses, why they are worked out across every time zone, and the Effective schedule block that describes the whole schedule.
- Combining rules Inside one rule everything must match. Across rules, any one is enough. That is the whole model.
- Writing a rule The three sections of a rule: dates, time of day, and days of week. What each accepts and what leaving one alone means.
