Thanks for pointing me to the package. Turns out it was intentional:

A caveat to Swift developers using official Docker Ubuntu images in the
future.

Looks like timezone files are in the ‘tzdata’ package. Maybe it got
uninstalled or was never installed as part of the base. An ‘apt-get install
tzdata’ might fix it.

It looks like it's /usr/share/zoneinfo on all Ubuntu versions:
alblue.local[~]$ docker run -it --rm ubuntu:14.04 find /usr -name
zone.tab
/usr/share/zoneinfo/zone.tab
alblue.local[~]$ docker run -it --rm ubuntu:16.04 find /usr -name
zone.tab
/usr/share/zoneinfo/zone.tab
alblue.local[~]$ docker run -it --rm ubuntu:16.10 find /usr -name
zone.tab
/usr/share/zoneinfo/zone.tab
This is the same that's coming from CFTimeZone.c:
https://github.com/apple/swift-corelibs-foundation/blob/2611dcd0d9b91fecace537838294bd85f0220503/CoreFoundation/NumberDate.subproj/CFTimeZone.c#L36-L39
Is it possible that the MacOS header is being included and defining
TZDIR before the CFTimeZone.c file is compiled?

We were seeing this on Travis too.
Specifically, on a Travis matrix build using
Swift 3.1.1 on a Ubuntu 16.04 docker image
running inside a Travis 14.04 VM.
The issue was specific to the Ubuntu 16.04
docker image; when I tested in Ubuntu 16.04
OS as a guest VM, the issue went away.

Yes, we’re discussing this one internally too
and trying to figure out what the right
answer is. Maybe the best solution for now is
to find a good mechanism to check the
underlying version of the OS and split it out
into a function as you suggest.

Good shout Simon, you
are right. I'm on
Sierra. Compare and
contrast:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/tzfile.h
#define TZDIR
"/usr/share/zoneinfo"
/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/tzfile.h
#define TZDIR
"/var/db/timezone/zoneinfo"
so I guess if I
installed the High
Sierra beta it would
work OK.
I hacked CF to force
it to
use /usr/share/zoneinfo
and TestFoundation
is much happier, but
that's not a
solution.

I also saw this error, I think its because the TZDIR is different in the
headers shipped with Xcode 9. Maybe the location of the timezone
directory was moved between Sierra and High Sierra. What version of
macOS are you testing on?
If it has indeed moved between 10.12 and 10.13 it may require a runtime
version check to dynamically return TZDIR.

Hi,
I'm seeing quite a lot of tests failing when
running the
TestFoundation target in Xcode. The failures are
timezone related.
Most simply, the code
let timeZone = TimeZone(abbreviation: "GMT")
is returning nil.
Walking through the CF code which sets things
up, it seems to be
trying to read the timezone database from
/var/db/timezone/zoneinfo/zone.tab which doesn't
exist on my macOS
system.
/usr/share/zoneinfo/zone.tab is there and seems
to be the right
location (?), but CF is picking up TZDIR from
tzfile.h which says:
#define TZDIR "/var/db/timezone/zoneinfo"
Any thoughts? I feel like I'm missing something
obvious and have gone
too far down the rabbit hole.
