Serving a practical purpose isn't "artificial" in my book.
I'm emphatically *not* saying that there's no such thing as "calendar time". I'm saying we need *separation* between "calendar" and "physical" time. (Which I thin we agree on?)
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.
Same principal developer :).
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.
The developer of both Joda and the jdk8 time.* system decided against, so there's that. (And I think it's pretty much undisputed that he *is* an expert and can actually make these trade-offs.) Regards,
