Working from bottom to top, some suggestions for making this post more useful:

• Tell us a bit more about the meaning (as used here) of "approximate." Is 15 days approximately "a week" ... or "a month?" Does 183 days approximate "a year?" What number of seconds become (roughly) "a minute?"
• Re "Any interest:" A clear and somewhat more expansive announcement would probably generate more interest.
• Re the address: better provided as a link -- see Markup in the Monastery and note also that while a site cited largely answers the questions, content here is durable; the Wise Monks who first offered guidance on the matter were concerned that off-site links may not be long-lasting.

IOW, I think you can sum up these observations as a call to "write a better tease" ...
        and, that said, yes, I, for one, find this so interesting¹ as to be persuaded to upvote a post whose content seems (to me) in serious need of improvement.

Update:   ¹ Where the value of "interesting" is "how does the code handle the many edge cases?"
