> BQ `DATETIME` = Calcite `TIMESTAMP` I don't see the connection. In Calcite, a timestamp is represented internally as an offset in milliseconds since epoch. In BigQuery, a timestamp is represented internally as an offset in microseconds since epoch. Apart from the difference in resolution, they're essentially the same. Of course, this can easily be re-interpreted as a `DATETIME` by assuming a default time zone, but I struggle to see how a Calcite `TIMESTAMP` is better mapped to a BQ `DATETIME` than to a BQ `TIMESTAMP`. -- This is an automated message from the Apache Git Service.
