Error – Unknown or bad timezone

Try re-uploading the wp-admin and wp-includes folders.

WordPress 2.8.6 + PHP 5.2.6-1

options-general.php line 145, WordPress use:
DateTimeZone('Etc/GMT-2');
instead of something like:
DateTimeZone('Europe/Paris');

Hack: adding ‘$tzstring=’Europe/Paris’;’

if (empty($tzstring)) { // set the Etc zone if no timezone string exists
	if ($current_offset < 0) $offnum = - ceil($current_offset);
	else $offnum = - floor($current_offset);
	$tzstring = 'Etc/GMT' . (($offnum >= 0) ? '+' : '') . $offnum;
	$tzstring='Europe/Paris';
}

I’ve search for a fix for this problem and nothing that is psted seems to work… I have this error on several of my blogs. Is there a good fix?

Same problem.
I changed the Homepage name in https://searchmade.com/wp-admin/options-general.php and got this error.

<b>Warning: timezone_open() [function.timezone-open]: Unknown or bad timezone (UTC+0) in /home/searchm8/public_html/wp-includes/functions.php on line 3444
Local time is 2010-03-06 11:36:43
Choose a city in the same timezone as you.
This timezone is currently in standard time.

Fatal error: Uncaught exception ‘Exception’ with message ‘DateTimeZone::__construct() [datetimezone.–construct]: Unknown or bad timezone (UTC+0)’ in /home/searchm8/public_html/wp-admin/options-general.php:163 Stack trace: #0 /home/searchm8/public_html/wp-admin/options-general.php(163): DateTimeZone->__construct(‘UTC+0’) #1 {main} thrown in /home/searchm8/public_html/wp-admin/options-general.php on line 163</b>

I again tried to change it again but now in the options-general page there is no text after there Timezone line except the above error. even the save btton is not there.

My configuration is
WPMU 2.9.2
PHP version 5.2.13
MySQL version 5.0.89

Can anybody please help.

Thanks

i meet the same situation as yours,but is “options-general.php on line 217”,and no “save changes”button

so i delete the line 217,save,upload,and then enter setting,button appears.so i can change the UTC to “hongkong”

save

thus “‘DateTimeZone::__construct() [datetimezone.–construct]: Unknown or bad timezone (UTC……” disappear.but some error appear

continue to change options-general.php,recover line 217,save,upload,refresh

return to normal

this is my way.i hope some help to u.
