Hi Maintainer

pandas FTBFS on 32-bit architectures with -D_TIME_BITS=64 (e.g. armel
and armhf), due to tests expected to fail, now passing.  I've copied
what I hope are the relevant parts of the log below.

The following is my first attempt at a patch, which would pass on
armel and armhf, but fail on i386 and hurd-i386, which are not built
with -D_TIME_BITS=64.

The following is my second attempt at a patch, which does not fail if
the expected test failures succeed.
