This is tested with LSB runtime test version 3.1.0, but also with many 
earlier versions (see http://www.freestandards.org/download/),

The semantics of the timezone variable are declared in Single Unix 
Specification Version 2 and 3:

  "The external variable timezone shall be set to the difference, in 
seconds, between Coordinated Universal Time (UTC) and local standard 
time." (Version 3)
(http://www.opengroup.org/onlinepubs/009695399/functions/timezone.html)

ctime() calls tzset(), where timezone is not set correctly.
