> Although currently we do not enforce any semantic meaning on the {{Long}}
> typed timestamps, we are actually assuming it to be non-negative while
> storing the timestamp in windowed store. For example, in
> {{RocksDBWindowStore}} we store the timestamp as part of the key, and relying
> on RocksDB's default lexicographic byte array comparator, and hence negative
> long value stored in RocksDB will cause the range search ordering to be
> messed up.
