I'm not surprised to see changes in the tz data affect regression tests 
like that. That's OK. Regression tests are designed to find changes, and 
when they find changes they're doing their job. The same thing will 
happen for sufficiently-extensive regression tests on Turkish time 
stamps in the next release, since we'll be changing Turkish time stamps 
in the next release too. Perhaps this will affect the PHP code as well; 
if so, the PHP developers will know how to deal with it.

Sure, but it's not more important than accuracy.
