I'm not the author of the DataExport components and, in fact, never used them. But scanning through the code I don't see usage of SQL parameters. Each exporter class, however, has a property FormatSettings with - among others - a DateFormat, TimeFormat and DateTimeFormat mask string. They default to the values of the SysUtils.DefaultFormatSettings, but if you need an ISO datetime, for example, you can set DateTimeFormat to 'YYYYMMDD"T"HHNNSS"Z"'.
