Start with Velox's Timestamp::toMicros in velox/type/Timestamp.h and the timestamp export path identified in the stack trace, including gatherFromTimestampBuffer and exportToArrow. Reproduce the PartialProject export with the timestamp value that triggers the overflow, then verify the export handles the case without the reported arithmetic error.
