- Since these tests use network resources, they are not enabled by default.
Set the environment variable TEST_HTTP_GET to actually do them.
- Do one request for each provider and check that they are all consistent.
(This works for me, yielding Europe/Amsterdam for all).
- Some providers return weirdly escaped data; strip out useless
escaping before splitting (there are no characters in correct
time zone names that need escaping)
- Add some tests for TZ splitting
