Thanks for your response. I'm still a noob in iReports and although I know C#, Javascript and a slew of other languages, java isn't in my back of tricks. Would I put code in the field def on the report? Right now, I'm just using a pattern to format the data. Will I need to add another library for the Joda-Time libraries? Sorry to be a pain, just not up to speed on the architecture of adding code to a specific field.
