Seriously, in this day and age?
Why not? Arguably, the field is too big, so it isn't wrapping sufficiently frequently to catch out lazy software developers before products actually ship. It's only going to be an insurmountable issue if the satellitle clock differs by 10 years, at which point you won't know whether it's a decade behind or ahead. That's more than enough margin, I'd have thought. Those who can't deal with wrapping integers should confine their professional activities to making web pages more annoying.
