Not at the moment. The reason is that with variables there, it is not possible to have compile time lifecycle management optimizations and Drools 5 was designed to use them. For Drools 6, I have an open JIRA to add support for that in case we find runtime optimizations equivalent to the compile time ones.

Hi,

Is it possible to use variables in temporal operators?

e.g. $eventA : EventA( this after[ 3m30s, 4m ] $eventB ) to be expressed as $eventA : EventA( this after[ $begin, $end ] $eventB )

where $begin and $end are either local rule variables or global variables

Regards
