Hmmm. It looks like this is a relatively old issue.

Once upon a time tzsetup had its own postinst, but it is now called from 
clock-setup. And clock-setup is not built for s390, I suspect because the 
installer is not supposed to mess with the system clock of an s/390 
system. 

So, currently tzsetup does get installed on s390 (as it is Priority 
standard), but the tzsetup script never gets executed. And that results 
in time/zone being empty.

But tzsetup definitely should be run, so we need some kind of special 
handling here.
