This does not appear to be accurate.
libc++ appears to always uses $TZ on POSIX-like platforms if it is set:
https://github.com/llvm/llvm-project/blob/788be0d9fc6aeca548c90bac5ebe6990dd3c66ec/libcxx/src/tzdb.cpp#L708
MSVC STL calls into __icu_ucal_getDefaultTimeZone. ICU's
ucal_getDefaultTimeZone uses the platform-specific way of getting the default
time zone, which on POSIX-like platforms does check getenv("TZ"), although of
course MSVC's STL would not likely be used on POSIX-like platforms.
