I am able to repro this and it is consistent across distros that have the new spelling. The // CoreFoundation/NumberDate.subproj/CFTimeZone.c
CFArrayRef CFTimeZoneCopyKnownNames(void) {
CFArrayRef tzs;
__CFTimeZoneLockGlobal();
if (NULL == __CFKnownTimeZoneList) {
CFMutableArrayRef list;
/* TimeZone information locate in the registry for Win32
* (Aleksey Dukhnyakov)
*/
#if TARGET_OS_WIN32
list = __CFCopyWindowsTimeZoneList();
#elif TARGET_OS_ANDROID
list = __CFCopyAndroidTimeZoneList();
#else
list = __CFCopyRecursiveDirectoryList();
#endif
// Remove undesirable ancient cruft
CFDictionaryRef dict = __CFTimeZoneCopyCompatibilityDictionary();
CFIndex idx;
for (idx = CFArrayGetCount(list); idx--; ) {
CFStringRef item = (CFStringRef)CFArrayGetValueAtIndex(list, idx);
if (CFDictionaryContainsKey(dict, item) || !__nameStringOK(item)) {
CFArrayRemoveValueAtIndex(list, idx);
}
}
__CFKnownTimeZoneList = CFArrayCreateCopy(kCFAllocatorSystemDefault, list);
CFRelease(list);
}
tzs = __CFKnownTimeZoneList ? (CFArrayRef)CFRetain(__CFKnownTimeZoneList) : NULL;
__CFTimeZoneUnlockGlobal();
return tzs;

TimeZone can't be initialized with some identifiers, e.g:
Also, knownIdentifiers method returns truncated identifiers list:
Known Identifiers list
```swift TimeZone.knownTimeZoneIdentifiers // will return the following array:The list above doesn't contain "Europe/Kyiv" or "Europe/Kiev" (old styly) TZ id.
