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.
