Java SimpleDateFormat parse issue into WEKA

I swear I'm using the correct date format but I keep getting a parse error when loading into WEKA.

"MonFeb2116:00:00+0000"
"EEEMMMddHH:mm:ssZ"

Here is an example dataset:

@RELATION example

@ATTRIBUTE tweetid STRING 
@ATTRIBUTE timestamp DATE "EEEMMMddhh:mm:ssZ"
@ATTRIBUTE I NUMERIC
@ATTRIBUTE a NUMERIC
@ATTRIBUTE cool NUMERIC
@ATTRIBUTE foo NUMERIC
@ATTRIBUTE bar NUMERIC
@ATTRIBUTE temp NUMERIC
@ATTRIBUTE class {POS,NEG}

@DATA

WEKA Error:

unparseable date "MonFeb2116:00:00+0000, read Token[MonFeb2116:00:00+0000], line 21

Have used the API documentation to double check - missing something?

Formatted date to separate tokens with space. Still not playing ball in WEKA...

Which default locale are you using? Using an English locale, the String "MonFeb2116:00:00+0000" should be parseable with the pattern "EEEMMMddHH:mm:ssZ". Note however, that the year will default to 1970, if not present in the pattern or parsed string. That is probably not what you really want.

Well, I don't know whether it'll sort everything out or not, but try changing hh (12-hour format) to HH (24-hour format). I'm not sure whether it'll be able to read a "day of the week / month name" without any spaces even so... do you have to get the value in that format? If you could put a space after the 3rd and 6th characters it would help...
