If you are struggling to find it here it is: %=date()%
Here is an example of setting a value with the current date.
Using the function: CBTA_IF_SETVALUE
Now this will return the current date into dd/mm/yy format.
If you want to use dot-delimited one you can use the following VB script:
%=day(now())&"."&month(now())&"."&year(now())%
and you can decide which goes first and which goes last and what is the delimiter.
Hope this is useful.
