Not sure I understand the question. core() does nothing special, it simply returns the inner matrix object without the dates for it. Irregular dates are a major headache, as well know. I think Diethelm put quite a bit of calendaring code into RMetrics (fSeries, or maybe fBasics ?) but I haven't used it ...
