Timezone Offset Issue

Yes it is ignoring the WordPress timezone settings. It is using your twitter timezone setting to set published date.

If you want to set it as per your WordPress Timezone you can customize plugin. Open ‘import-twets-as-posts.php’ file and replace the following code:

$tweet_post_time = strtotime($tweet->created_at) + $tweet->user->utc_offset;

To:

$tweet_time = strtotime($tweet->created_at);
$wp_offset = get_option('gmt_offset');
if($wp_offset){
  $tweet_post_time = $tweet_time + ($wp_offset * 3600);
} else {
  $tweet_post_time = $tweet_time + $tweet->user->utc_offset;
}

Hope this will help you.

Also added option under plugin’s setting to set tweet publish date as per WordPress timezone in updated version 1.5. Let me know if this works for you.

Just tested. Works great.
