I can currently not be asked to boil the example down, since it emerges from a
fairly large project. However, I can confirm this in trunk v. 20150502.

I reported to overseers that the problem was not in Bugzilla, per comment 34,
but I don't know if they found what was altering the local timezone. I can add
a workaround in Bugzilla itself, if that helps. Frank?
