  @brief Returns E8601DT26.6 if compatible else DATETIME19.3
  @details Per our experience in [Data Controller for SAS]
  (https://datacontroller.io) deployments, the E8601DT26.6 datetime format has
  the widest support when it comes to pass-through SQL queries.

  However, it is not supported in WPS or early versions of SAS 9 (M3 and below).
