Yes, meant to mention that OS X is largely BSD derived, and certainly not Linix derived. Though, I am under the impression that OS X was derived from NetBSD, not FreeBSD. An aside, I ported NetBSD's strptime to (modern at the time) C++ in internal code at a previous employer, because we needed a cross platform DateTime parsing routine. (And strptime is not posix and not generally available to posix systems). To the best of my knowledge, there's still a bug in handling timezone offset parsing. Its been too long for me to remember exactly, but circa 2008, the man page definitely did not match the actual source behavior.
