Proposed change to time zone northamerica file: deferred Cuban DST

[Arthur David Olson]

Since this affects current time stamps, it's probably best to get a best
guess out the door rather than wait for documentation. Here's a proposed
change to the time zone package "northamerica" file to reflect the deferred
start of DST in Cuba.

+ # I'm in Maryland which is now observing United States Eastern Daylight
+ # Time. At 9:44 local time I used RealPlayer to listen to
+ # <a href="http://media.enet.cu/radioreloj">
+ # http://media.enet.cu/radioreloj
+ # </a>, 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.
+ 
+ # From Dirk Losch (2008-03-05):
+ # I've been informed that the DST in Cuba will begin at 30th of 
+ # March 2008. The information is based on IATA.
