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
