I was planning to rely completely on Jodatime there, and I believe its default behavior is to use the local timezone of the machine it is on. ISO time encodes the time zone, and jodatime does the conversions back and forth, taking it into account.
Should this be a pig config field? You can specify a timezone in jodatime, so that should work out ok, it would limit hadoop node shenanigans.
