> ISO8601.java uses the default DecimalFormat constructor which uses locale 
> specific DecimalFormatSymbols. Runnning Jackrabbit in an Indian locale the 
> format() produces a date using DEVANAGARI numeric digits. The saved version 
> (UTF-8) encoded is much longer than usual and is not transportable. On 
> parsing, DecimalFormat works, but TimeZone.getTimeZone("GMT+09:30") (with 
> Indian numeric digits) fails and null is returned from ISO8601. Later this 
> traceback occurs.
