> `Instant.parse()` is expected to use the offset zone pattern `+HH:mm:ss` (as defined by `DateTimeFormatterBuilder.appendOffsetId()`), but it fails to parse hour-only offsets such as `+02`. This is because the actual implementation uses `+HH:MM:ss` as the pattern. While replacing the pattern in the implementation as with the specification would allow hour-only offsets, it would also introduce compatibility issues, i.e., printing would omit the minutes field when it is zero. So, it is preferable to update the specification to match the implementation. A CSR has also been drafted for this change.
