  Definetely wrong! The first 2 lines must be identical - they are
expexted to be your timezone (MSK, in my case).  I got different results on different glibc2-based linux systems, but
all
was wrong. On Debian 2.0, e.g.:
-----
MSK
EET
EST
-9200
-----
  MSK is Ok here (it is output from strftime()), but other lines (global
variables) are wrong.  Thomas Lockhart gave an idea that global variables cannot be used at all
in thread-safe library, so the problem is - how to detect glibc2 at
configure stage, and how to patch date/time arithmetic in postgres. I am
working on it...
