Christopher Brecht commented on DROOLS-1917:
--------------------------------------------

This feature would be very nice to have. Is there an estimated time, when this will be implemented? Or is this not possible?

> It would be cool if it were possible to use expressions, and bound variables in particular, in time intervals for temporal operators. Something like this:
> rule "Sound the alarm with parametric delay"
> when
>     $f : FireDetected( )
>     not( SprinklerActivated( this after[expr: $f.start, $f.end] $f ) )
> then
>     // sound the alarm
> end
> A similar request was made for the interval-based timer in this issue:
> https://issues.jboss.org/browse/JBRULES-3402
