Unix API makes an habit of this kind of thing. Often, it is because the feature was not designed from the start, and then it was shoehorned into existing APIs with a global state, changing their behavior in a subtle and dangerous manner. Locales are one of the worst offenders. They are the reason you could get, around the turn of the century, the interactive interpreter for the OCaml language accept “let pi = 3.14;;” and output “val pi : float = 3.”. Yet, (some) localized functions now exist with a _l variant taking a locale_t argument, but no such thing exists for timezone. Regards, -- Nicolas George
