If you go to Plug-Ins and Edit, then you can add one space to the code to fix this small and odd bug.
Look for this line:
if ( $show_date ) echo '<span class="post-date">' . get_the_time( get_option( 'date_format' ) ) . '</span>';
And change it to this:
if ( $show_date ) echo ' <span class="post-date">' . get_the_time( get_option( 'date_format' ) ) . '</span>';
