By "ordinary developers", you mean non-Haskell developers? Because the standard Haskell time library used Haskell's rich type system to model the semantics of time correctly long before JodaTime existed. Some people like JodaTime, but I would be very hesitant to use it until I see a proof that it at least comes close to the Haskell time library, and I am skeptical. I have heard that the Smalltalk time library got the semantics of time right long before even the Haskell time library, but I have not seen it myself in detail. -Yitz
