```
    Takes two offset times and returns a list of multiples of the frequency offset from the effective nominal time that occur between them. The caller should make sure that startCal is earlier than endCal.
    As a simple example, assume its the same day: startCal is 1:00, endCal is 2:00, frequency is 20min, and effective nominal time is 1:20 -- then this method would return a list containing: -20, 0, 20, 40, 60
    
    Parameters:
    startCal - The earlier offset time
    endCal - The later offset time
    eval - The ELEvaluator to use; cannot be null
    
    Returns:
    A list of multiple of the frequency offset from the effective nominal time that occur between the startCal and endCal

                            ELEvaluator eval)
```
    Resolve the offset time from the effective nominal time
    
    Parameters:
    n - offset amount (integer)
    timeUnit - TimeUnit for offset n ("MINUTE", "HOUR", "DAY", "MONTH", "YEAR")
    eval - The ELEvaluator to use; or null to use the "current" eval
    
    Returns:
    A Calendar of the offset time
