Subject: [PATCH] Set build date from SOURCE_DATE_EPOCH
|
|
|
|
Allow to override build date with SOURCE_DATE_EPOCH
|
|
in order to make builds reproducible.
|
|
See https://reproducible-builds.org/ for why this is good
|
|
and https://reproducible-builds.org/specs/source-date-epoch/
|
|
for the definition of this variable.
|
|
|
|
This PR was done while working on [reproducible builds for
|
|
openSUSE](https://en.opensuse.org/openSUSE:Reproducible_Builds).
