Bug-Description:
Roman Rakus ee79c04
Roman Rakus ee79c04 
Systems that use tzset() to set the local timezone require the TZ variable
Roman Rakus ee79c04 
to be in the environment.  Bash must make sure the environment has been
Roman Rakus ee79c04 
modified with any updated value for TZ before calling tzset().  This
Roman Rakus ee79c04 
affects prompt string expansions and the `%T' printf conversion specification
Roman Rakus ee79c04 
on systems that do not allow bash to supply a replacement for getenv(3).
