commit 5181f1f86a4d4c2ac09a540285c938fe2c2fa262
Author: Bernhard M. Wiedemann <bwiedemann@suse.de>

    Tests: make tests pass with SOURCE_DATE_EPOCH set
    
    Fix tests to account for commit 243aed52 (cmTimestamp: Support
    SOURCE_DATE_EPOCH to override current time, 2017-01-25).
    
    In openSUSE we are running the test-suite as part of the build and that
    failed in these two places when building everything with
    `SOURCE_DATE_EPOCH` set.
