I am attempting to use the after[start, end] construct with two time values being returned in milliseconds. We are effectively using Drools 5.3 (BRMS 5.3.1). Here is what I have (field names changed, etc due to nature of data): //--------------------------------------------- global String someInsertedConstant; global Calendar myCurrentTime; // calculated just before inserting as global. rule "compare time in millis" dialect "java" when $someObject : SomeObjectClass ( field1 == someInsertedConstant, field2 == null, myCurrentTime.timeInMillis after[15m, 96h] someObject.getTime().getTimeInMillis ) from entry-point "SomeEntryPoint" then System.out.println("Boo-yah!!!"); //------------------------- This does not send out a Boo-yah!!! as I would expect, when myCurrentime is 15 minutes or more past someObject.getTime(). However, I have another rule just like this, where the only difference is the after is [0m,15m] instead, and it gives a Boo-yah!!! as it should when myCurrentTime is up to 15 minutes past someObject.getTime(). Both rules are together in the same package. Am I missing something here? In the first case, "after[15m, 96h]", I can change that line to manually subtract the two times as longs and compare against being >= 900000 and it fires as it should. This appears to be a bug, but I am not entirely sure as I am fairly new to the rule world. What am I missing?
