I'm a happy user of your plugin. However, I noticed that because I don't live in GMT, the plugin shows the wrong timestamps for me.
If you ever consider updating the plugin, here's the change:
$cron[ $timestamp ][ $hook ][ $key ][ 'date' ] = date_i18n( $date_format, $timestamp + 3600*get_option('gmt_offset'));
I added " + 3600*get_option('gmt_offset')"
What it does is add "one hour in seconds" times the gmt_offset, to the timestamp.
Again thanks for the plugin.
