Additional information available:

SQL92VMS

 Specifies that the DATE and CURRENT_TIMESTAMP data types are
 interpreted as SQL92 format.  The SQL92 format DATE contains
 only the YEAR to DAY fields.

 Specifies that the DATE and CURRENT_TIMESTAMP data types are
 interpreted as VMS format.  A VMS format data type is compatible
 with Rdb/ELN and versions of Rdb/VMS prior to Version 4.1, but
 cannot be used in date-time arithmetic.  The VMS format DATE and
 CURRENT_TIMESTAMP contain YEAR to SECOND fields.

 The default is VMS.
