Hi,
AFAIK, joda-time can't parse the timezone. [1]
"*Zone names*: Time zone names ('z') cannot be parsed."
I don't know why that's the case; maybe someone else here can pitch in. I
recently had to use java.util.Date and friends to cope with this same issue.
For completeness, here is the stack trace that I think you're seeing:
Exception in thread "main" java.lang.IllegalArgumentException: Invalid
format: "Fri, 06 May 2011 16:30:38 UTC" is malformed at "UTC"
at
org.joda.time.format.DateTimeFormatter.parseDateTime(DateTimeFormatter.java:683)
at TimeFormats.parse(TimeFormats.java:17)
at TimeFormats.main(TimeFormats.java:24)
Cheers,
James

Achieve unprecedented app performance and reliability
What every C/C++ and Fortran developer should know.
Learn how Intel has extended the reach of its next-generation tools
to help boost performance applications - inlcuding clusters.
