You may have to define your own version of temporal operators or at least
to replace the parser for the temporal operators' parameters, i.e., what is
written between the brackets.
I guess that in your domain, a month is not an absolute interval but depends
on the starting point. This makes it more difficult if you intend to use
a temporal relation based on arbitrary starting points. In this case, even
a full redefinition of (some of) the temporal operators might be
necessary, where
distances off some point in time depend on that point in time. Can you
provide a consistent definition, at least for those temporal operators you
intend to use? The definitions in Drools Fusion are complete; see what you
would need to have with months (and years) in their parameters.
