## Details
| Var | Status | Description | Notes |
|-----|--------|-------------|-------|
| `.toDays` | ✅ supported | Return duration length in whole days | Requested in issue #1019 for bucket/day calculations. |
| `.toMillis` | ✅ supported | Return duration length in milliseconds | Requested in issue #1019 for instant differences. |
| `Duration/between` | ✅ supported | Duration between two instants | Requested in issue #1019 for millisecond/day differences. BUG GAP-J19: java.util.Date inputs are accepted instead of rejected. |
| `Duration/ofMillis` | 🔲 candidate | Construct duration from milliseconds | Useful companion for bounded Duration support. |
| `Duration/parse` | 🔲 candidate | Parse ISO-8601 duration string | Useful but lower-priority than between/toMillis/toDays. |
