--------------------------+-------------------------------------------------
 WordPress 2.8 installed on PHP 5.1.6, Timezone Option functionality does
 not work (wp_timezone_supported check reverts to pre-2.8 timezone option
 functionality).

 The wp_timezone_supported() function checks for the following PHP
 functions (functions.php, line 3173):

 date_default_timezone_set (requires PHP >= 5.1.0)
 timezone_identifiers_list (requires PHP >= 5.1.0)
 timezone_open (requires >= PHP 5.1.0)
 timezone_offset_get (requires PHP >= 5.1.0)

 However, in PHP 5.1.6, timzeone_identifiers_list, timezone_open, and
 timezone_offset_get appear not to be available.

 Apparently, timezone_identifiers_list
 [http://bugs.php.net/bug.php?id=34373 requires a custom compile option].

 The other two options appear to have similar issues (Date PHP4 module not
 enabled).

 Also, it appears that timezone_offset_get
 [http://bugs.php.net/bug.php?id=44742 may not work in PHP versions below
 5.2.6].
