<h3>What else you need to know</h3>
This plugin utilizes services provided by <a href="http://timeanddate.com" rel="nofollow ugc">TimeAndDate.com</a> and is brought to you with their friendly permission.
TimeAndDate’s condition of use stipulates a maximum of 6 clocks per page. In future this limit will be removed however for now it is important to stick to it as each clock creates a connection to their server (and ours). TimeAndDate also requires a separate link to their site if more than two clocks are used.
