I think it is by design. You can read the FLIP, it says: *Time Semantics*:
- PTFs support event-time semantics only. - Processing-time doesn’t go well with batch mode and thus a unified API should built on event-time. The proposed onWatermark timers allow for making processing nevertheless and key-independent. An onWatermark should cover most processing time use cases. But I think if the PTF doesn't implement the `onTime` method, it means the function doesn't care about the time. In this case, we can just convert directly in batch mode.
