Thank you kindly for the offer Craig, but I cannot accept. Unless this code
is part of an open source project with an ASF-style license as I cannot have
our company deal with any legal issues.

FYI, I am not having much luck using the JRE's SimpleDateFormat to parse
xs:duration instances. SimpleDateFormat can create strings for dates, no
problem but not string to dates. Still playing around with:

Hi,

I am using a custom Duration utility class to handle duration strings
once they have been unmarshalled. Basically, it contains a method

public static Duration parseDuration( String str ) throws ParseException

to parse a duration string, and performing conversion to year, month,
day etc. fields with an accessor for the long value as well. Mail me if
it would be of help.

OK. So essentially you are just interested in the time span in terms of
some fixed measure. Thank you for the input.

BTW, what's your plan if you see "1 month"? How many seconds should be
one month?
