FAIL: test_invalidation_mode (test.test_py_compile.PyCompileTests)

This failure looks suspicious. I looked at the code, and the tested function behaves differently depending of the SOURCE_DATE_EPOCH environment variable is set.

Aha! I found something:

$ SOURCE_DATE_EPOCH=1530605018 ./python -m test -j0
