TZ=... date affected PROMPT_COMMAND

[jidanni]

Never thought that putting TZ here would infect my prompt,

21:07 ~$ date
Wed Apr 16 21:07:54 CST 2008
21:07 ~$ TZ=America/Chicago date
Wed Apr 16 08:08:07 CDT 2008
08:08 ~$ set a b c
08:08 ~$ date
Wed Apr 16 21:08:22 CST 2008
21:08 ~$

all the way until the next non built-in command.
Need to do sh -c 'TZ=America/Chicago date'
if one doesn't want their prompt affected.

(On the other hand, what I do in .bashrc is black magic to me too:)
