asterisk users - Mar 2007 - New Linksys SPA Daylight Saving Time Rule for US/Canada

To work with the latest change to the US/Canadian DST, I made a new Daylight
Saving Time Rule for my Linksys SPA-9XX phones.  

start=3/7/7/02:00:00;end=11/1/7/02:00:00;save=1

As I could see no way to tell the phones to begin DST on the second Sunday
in March, I assumed that the second Sunday would always be at least on or
after the 7th of the month.  

Let me know if you see any obvious flaws to my logic, or the rule itself.

Thanks.
