current_time() does not correctly retrun localized time

[hiromasa]

When you set you set timezone using a city name, current_time() function in functions.php does not return correct local time.

Cause:

When you get gmt_offset(), the wp_timezone_override_offset() hook offsets the timezone again after date_default_timezone_set sets the timezone (this happens only when timezone_string exists).

Example 1:

Your timezone is set to "Tokyo" (UTC+9), using the city name. wp_options will contain:

timezone_string	Asia/Tokyo
gmt_offset      ''

Code below will incorrectly retun UTC+9+9.

<?php echo date('Y-m-d H:i:s', current_time( 'timestamp' )); ?>

Example 2:

Your timezone is set to "UTC+9" (WordPress 2.9.1 RC1). wp_options will contain:

timezone_string	''
gmt_offset      9

Code below will correctly retun UTC+9.

<?php echo date('Y-m-d H:i:s', current_time( 'timestamp' )); ?>
