Test failures in the MRI 1.9 suite (Time class) when TZ is set #948
Description
On a fresh checkout and build of JRuby, running rake test:mri19 results in a number of test failures related to timezones. When I have TZ=Europe/London I get the following output at the end of the test run:
1) Skipped:

When I export TZ=UTC I'm left with just the 9 skipped tests, and no failures.
I'm running Ubuntu 12.04, and the version string of my JRuby build looks like:
