Recurrence Expander Turn RFC 5545 RRULEs and cron expressions into exact UTC instants. IANA timezones and daylight saving are handled correctly. The two hard cases are flagged by name. A spring-forward time that never happens is flagged nonexistent. A fall-back time that happens twice is flagged ambiguous. Results are deterministic and reproducible.

The receipt binds the input hash, the output hash and the engine versions. WHAT YOU ARE NOT BUYING: secrecy. You can expand the rule yourself and check every instant we return.
