Beause the leap second is entirely artifical, invented to keep the *calendar* ("Earth" time) in sync with *physical* time.
Serving a practical purpose isn't "artificial" in my book.
[1] Bascially before JodaTime made ordinary developers aware of just how complex this Time/Date stuff really is and the importance of clearly separating the concept of "calendar" time vs. "physical" time.
Yeah, that's a really awesome library, and well worth looking at if you want fresh time API ideas.
Actually, the Java 8 standard "time" library is -- in many ways -- even better, it's been simplified to account for the fact that 99% of people don't actually need to account for e.g. Julian (or $OTHER) chronologies. If you need that kind of functionality, you're already out in the weeds and you probably need to implement your own library *anyway*.
I haven't looked at Java 8 date/time yet, I hear it's heavily influenced by Jodatime so it's pretty likely that you can draw the same ideas from that. I'd still start with Jodatime, just to have a better chance of interoperability with needs for alternate calendar systems. Mostly to glean a list of potentially useful data types, and which data fields are relevant to each.
