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.
|
||
|
|
|
||
|
|
It prioritizes the variable over mtime
|
||
|
|
because openSUSE's `tallow` package touched a .md file with a patch.
