This is what I've decided on based on Eric's and Diego's examples:

I learned a lot from this. Many thanks to everyone for sharing their ideas.

One gotacha: The STRINGIN record translates the time stamp to a strftime conversion, %M for testing and %j for production. That output is still a string, "001" through "365". However, CALC takes this string and casts it into an integer. I haven't confirmed this assumed cast from base source code yet, so correct me if I'm wrong.
