I've changed the sources to use SOURCE_DATE_EPOCH has reference. The
string embedded into the version info is build using the reference
timestamp in UTC. Maybe there should be a SOURCE_DATE_UTC build from
SOURCE_DATE_EPOCH using `date ... -u` since RFC2822 contains a timezone
making reproducible builds hard.

$ date -d "$(dpkg-parsechangelog --count 1 -SDate)"
Tue Jun 16 11:43:42 CEST 2015
$ export SOURCE_DATE_EPOCH=$(date -d "$(dpkg-parsechangelog --count 1
-SDate)" +%s)
$ date -d @$SOURCE_DATE_EPOCH -u
Tue Jun 16 09:43:42 UTC 2015
$ ./src/apt-dater -v
apt-dater 1.0.2 - Tue Jun 16 09:43:42 UTC 2015


The upstream part is fine but adding SOURCE_DATE_EPOCH in debian/rules
ist still missing.


HTH,
