    Description copied from class: PeriodicWork
    
    Gets the number of milliseconds between successive executions.
    Hudson calls this method once to set up a recurring timer, instead of calling this each time after the previous execution completed. So this class cannot be used to implement a non-regular recurring timer.
    IOW, the method should always return the same value.
