How access value of the system value using Digital Metaphors ReportBuilder RAP

I'm using Digital Metaphors ReportBuilder in Delphi 2007. I'd like to access the system date (the value of the now function in Delphi) using RAP, but get an undeclared identifier error when attempting to compile in the Report Builder designer. What is the best way to get the system date i开发者_运维问答nside of RAP?

From RAP.HLP

Delphi = RAP Date = CurrentDate Time = CurrentTime Now = CurrentDateTime
