"UN English" generally follows British/Oxford usage, although there are a few exceptions: writing "Mr." with the full stop, "sulfur" rather than "sulphur", "1.30 pm" (not 1:30 pm or 13:30) etc.
I think it's a decent compromise. All the Zs make it look weird to British readers, and all the Us make it look weird to Americans.
