Time Zone and Countdown mismatch/error

Hi

I have installed the great T(-) plugin. However, the time zone is set for London yet the countdown is approximately 23hours behind were it should be.

My website is http://www.oakfurniturehub.co.uk

Can someone offer me assistance with this issue.

Regards

John Gardner
