---------------------------------------------------------------------- (0006801) eggert (reporter) - 2024-05-24 22:56 https://austingroupbugs.net/view.php?id=1797#c6801 ---------------------------------------------------------------------- > A conforming C application cannot set tm_zone as no such thing exists. No, there are many ways a conforming C application can set tm_zone. The several real-world applications I cited in https://austingroupbugs.net/view.php?id=1797#c6793 all set tm_zone by calling gmtime, and these apps work fine on GNU/Linux, macOS, z/OS, etc. This is common practice. Obviously we disagree about how to interpret POSIX. I find the overly-strict interpretation unconvincing because (a) significant real-world implementations have disagreed with that interpretation for decades, (b) it's easy to find real-world applications that rely on these implementations' behavior, and (c) it's hard to find real-world applications that rely on the overly-strict interpretation. This is not a new issue. What's new is that this lack of clarity or glitch in the standards is being brought to the standardization bodies' attention.
