Cuban time

I'm in Maryland which is now observing United States Eastern Daylight Time. At 9:44 local time I used RealPlayer to listen to http://media.enet.cu/radioreloj, a Cuban information station, and heard the time announced as "ocho cuarenta y cuatro" ("eight forty-four"), indicating that Cuba is still on standard time. If I use Internet Explorer to view http://www.radioreloj.cu, scroll to the bottom of the page, and wait for the animated reloj (watch) to appear in the lower-right-hand corner, it shows 9:44--what we'd expect with the current time zone database stuff. Does anyone have an official reference for the March 30, 2008 Cuban DST start date we've seen on the mailing list? --ado
