[rules-users] Date arithmetic in when part

[lhorton]

Interesting.  I tried to use this syntax to find out if a date is older than
"now" using this source:

$p2: Person( $dob2: dob before[3d] new Date() )

but I get and exception: org.drools.RuntimeDroolsException: The 'before'
operator can only be used to compare one event to another, and never to
compare to literal constraints.

any idea how to compare to "new Date()"?  I had already written a function
to do this date comparison, but will use the Drools syntax instead if I can
get this to work.
