OT T-shirt

I have a query on OT Tshirt when the site is down for maintenance, a countdown clock is shown as all zero's. Where is the clock configuaration or is this just for show and it does not really work.

Is it possible to put a clock there if it is just part of the design

Please change $enddate line 47 on file path: root/templates/ot_tshirt/offline.php
