[rules-users] Time unit step-size inside rule files.

Hello out there, is it possible to change or extend the existing time unit step-size like [h,s,ms] used inside the rules? They all seems to have a fixed (logical) relationship (e.g. 1 s = 1000ms). Unfortunately we have a different time representation in our application. We can rebuild the time model using the smallest units as pseudo time reference but this makes the rules hard to write / read as every user has to know how much “smallest-time-units” represents a real world second. Thank you very much Thorsten
