I disagree on this order, at least for Linux systems. the tzdata database is well managed on major Linux distributions and should be used for this reason. There's no guarantee that an individual sysadmin will have OS updates up-to-date. If, on Linux, the pytzdata module is not installed unless explicitly called for, that would define pytzdata as high specificity, ergo it should override the lower specificity of the OS-provided data. The normal case on Linux will happily use the well-managed and frequently-updated tzdata.

I don't care as long as pytzdata is a third party module. I do care if it belongs to the standard library.

I don't want to see a python and perl/java/foo application seeing different local times.
