Running the following locally fails for me:

    $ SOURCE_DATE_EPOCH=`date` ./python -m test test_py_compile test_compileall

So my guess would be that this is a test suite error where we're not
handling the "running in a reproducible build environment with
SOURCE_DATE_EPOCH already set" case.

Cheers,
Nick.
