 I'm experiencing some issues with Wordpress timezone handling.

 If we have a look at the current_time function, we'll see that when called
 with the 'timestamp' parameter it returns time() plus the GMT offset.

 {{{

 else $d = time() + (get_option('gmt_offset') * 3600);

 }}}

 However, if time() is not really returning the number of seconds till GMT,
 but to the timezone set in the server computer, it returns an incorrect
 value.

 Test code as follows.
 My timezone is GMT - 3. GMT for the example is 00:58:05

 {{{

 echo current_time('mysql');
 echo date('Y-d-m H:i:s', current_time('timestamp'));

 // will return
 // 2007-08-28 21:58:05 (GMT -3: correct)
 // 2007-28-08 18:58:05 (GMT -6!)
 }}}

 The problem has been solved by resetting the TZ enviroment variable.

 {{{

 putenv('TZ=');

 echo current_time('mysql');
 echo date('Y-d-m H:i:s', current_time('timestamp'));

 // returns
 // 2007-08-28 22:02:56 (GMT -3)
 // 2007-28-08 22:02:56 (GMT -3)
 }}}

 My setup:

 {{{
 guillermo-rauchs-computer:~ guillermo$ php -v
 PHP 5.2.2 (cli) (built: May  4 2007 17:56:56)
 }}}

 {{{
 guillermo-rauchs-computer:~ guillermo$ uname -a
 Darwin guillermo-rauchs-computer.local 8.10.1 Darwin Kernel Version

 }}}

 Using latest trunk

 Haven't reproduced this in more computers. Can anyone do so?
