The fix is rather simple.  In the source file Analyzer.java in 
package com.sun.electric.plugins.irsim is the method 
newVector().  Find this line of code:

        afterSV.value = curTime + stepSze - insertTime / cmdFileUnits;

Change it to read:

        afterSV.value = (curTime + stepSze - insertTime) / cmdFileUnits;
