How to change the date expression to numeric after creating 'New Calculated Item' in SAS VA

[c4th1]

Hi, I am trying to do new calculated item in the Report Designer to calculate 'now() - timestamp' to give a total number of days. Can someone please advise how do I do the calculation. And how to show the result in numeric?

Thank you.

It is a little cumbersome, but you can use the DayOfYear and Year functions to return numeric values from the two dates ('now' and 'timestamp').  Also you have to wrap 'Now()' in a DatePart() function:

365*( Year(DatePart( Now() )) - Year( timestamp ) + DayOfYear( DatePart( Now() )) - DayOfYear( timestamp )

I checked if a simpler calculation would work:

DatePart( Now() ) - timestamp

But it did not.  I think this is because the underlying SAS date value is not a supported format for VA content, but I can check on it with some folks I know in development.
