system timezone regression failure

Building 8.4 on a client's system, I get a regression failure apparently
due to some difference between the system's timezone DB and what out
regression tests expect, as shown below.

I'm wondering if we should not disable the timestamptz regression test
when we configure with the system timezone db. I guess i could patch the
SRPM by providing an alternative result file - not sure if it's worth it
though.

cheers
