The build date is embedded in libITKCommon-5.2.so.1: https://tests.reproducible-builds.org/debian/rb-pkg/bookworm/amd64/diffoscope-results/insighttoolkit5.html http://www.itk.oThe·URL·of·projeThe·version·at·configuration·tim2021-12-31·08:41The·date·of·conf ... vs. http://www.itk.oThe·URL·of·projeThe·version·at·configuration·tim2022-01-01·10:41The·date·of·conf ... While CMake respects SOURCE_DATE_EPOCH, it still can produce a different date depending on the timezone of the running system. Applying the attached patch explicitly sets the timezone to UTC and should result in a reproducible build for the testing/bookworm suite. There may be other reproducibility issues caused by changing build path for sid tests that are not addressed by this patch. Thanks for maintaining insighttoolkit5! live well, vagrant
