> Change the representation of TimestampVectorBatch to be in UTC rather than local time.
> The advantages are:
> * More closely matches the SQL semantics of timestamp without timezone.
> * Allows accurate representation of all values including the ones that occur
>   during the local leap forward/back for daylight savings.
> * One less timezone conversion.
