The current scope of "arbitrary granularity" is too broad: 1. Granularities such as `yyyy`, `yyyyMM`, and quarters lack a day field, making it impossible to parse them into valid dates. 2. Non-unique fields—such as AM/PM or week-of-month—also fail to support round-tripping. 3. The `Y` specifier represents a week-based year but increments based on the standard calendar year, leading to missed partitions. 4. Enumerating `(start, end]` intervals point-by-point at millisecond or nanosecond granularity can cause an explosion in planning time and memory usage. -- This is an automated message from the Apache Git Service.
