If I'm not mistaken,
-0300 is Greenland and most of Brazil, and
-0330 is Newfoundland, Canada's easternmost province,
-1100 covers the Pacific Ocean just west of Hawaii and I don't think the 
International Date Line comes into play.
-0200 might be useful, just nips the east coast of Brazil and squeezes 
between Iceland and Greenland
