Very good and Thank you.  I also offer my assistance if you would like 
it to test some of rmetrics or help fixing some of the minor bugs that 
are found.  Has an consideration be given to changing the DST calendars 
to be more like the holidays where the DST is calculated using rules for 
regions rather than the hard coded date vectors?  The current method is 
simple and efficient for code but looks difficult to maintain.  The 
rules that can be derived from the website above might allow easier 
maintenance in the future.

Take care.
Joe
