While working on reproducible builds for openSUSE, I found that our
librcc and librcd packages produced different results in IBS than in my local verification builds.

The %changelog section in the .spec had such diff:

-* Fri Feb 12 2010 csa@dside.dyndns.org
+* Sat Feb 13 2010 csa@dside.dyndns.org

because the .changes file had

-------------------------------------------------------------------
Sat Feb 13 00:00:00 MSK 2010 - csa@dside.dyndns.org

- Update to 0.1.13

and apparently my (Leap 15.6) machine was able to resolve the MSK zone to 1266008400 but IBS fell back to UTC.

This is similar to #1047 but different.
