This is covered in the Makefile: look for the strings "posix_right" and 
"right_posix".

Debian still uses the scheme that TZDB used before 1998. That scheme has 
problems (see the Makefile comments before the "right_posix:" lines) but 
I guess they're willing to live with the problems.

To some extent this stuff will become obsolescent once leap seconds are 
discontinued. It'll still be an issue for old timestamps of course.
