Note: I triggered rebuilds on reproducible-builds and now the failures on testing/amd64 and unstable/amd64 are both as follows:
-2018-11-03 09:23:38.000 -2018-11-03 09:23:38.000 -2018-11-03 09:23:38.000 +2020-11-03 09:23:38.000 +2020-11-03 09:23:38.000 +2020-11-03 09:23:38.000 Sorry, I believed this was related with the build date, but now I'm greatly confused. Thanks.
