String tokenizer problem

I'm having some trouble with the StringTokenizer. As far as I can tell
there is something wacky going on due to the + or : in the delimiter.
I have the following string:
Sep 29, 2009 7:00 PM GMT+00:00 Sep 30, 2009 7:30 PM GMT+00:00

I am using "GMT+00:00" (no quotes) as the delimiter.

The String#split method correctly splits the string in to the array
elements using a simple regex:
String[] tokens = text.split("GMT\\+00:00");

The StringTokenizer splits on the first double zero in 2009 and then stops
at the colon in the time next:
StringTokenizer t = new StringTokenizer(text, "GMT+00:00");

The 1st two tokens are:
Sep 29, 2
9 7

Has anyone seen this behavior before? Am I missing something obvious?

Thanks,
