Hi Fabian,

Have you tested this patch? My understanding is that debhelper sets SOURCE_DATE_EPOCH but make(1) does not. In general, debian/rules is a plain Makefile and shouldn't assume higher-level tools set anything extra.

So this patch wouldn't work; you need to add a line:

export SOURCE_DATE_EPOCH = $(shell dpkg-parsechangelog -SDate | date -f- +%s)

near the top of debian/rules.

Or you can wait until #824572 is fixed, which I just filed. Then your patch might work without needing to add the extra line above.
