Comment 8 for bug 1234649

as commented on IRC, I don't believe an SRU is warranted for only this bug. It's not user-affecting, sbverify is only used in our test environment; and having confirmed that sbverify is buggy, that can be worked around by e.g. using faketime. We probably want that as an interim solution *anyway*, because any SRU of sbsigntool is going to be blocked by the one already in progress, needed to fix other issues that would block building of the shim-signed package.
