Hi Jim, My UDF is currently so simple that I'm not sure you need it (or want it).
It basically just rounds a timestamp value with ISO 8601 periods asRoundTimestamp(timestampvalue,'PT10M'). I would be more than happy to contribute to your project rather than building our own :). Is the repo public? Regards, -Stefan On Sun, Jul 19, 2015 at 6:18 PM, Jim Bates <jba...@maprtech.com> wrote: > Maven will typically create a jar for class and a jar for source when told > to do so.
