News Show Pro and K2 - date issue

I am not sure where the date function is off. My home page is showing 1 day off (ie - Friday Dec 4 instead of Friday Dec 5).

The template, joomla are all up-to-date.

TIA

Still waiting for help. I can change the dates to one day ahead - but that seems idiotic to do in the event it mysteriously corrects itself.

But this problem still persists - no matter what date I have - it makes it one day before.

If you need my system information:

I submitted this as a support ticket now. The site needs to be fixed and cannot wait.

Hi

This problem is most probably because of Your set time for server and database. I believe they are different. That's a common issue and we have provided a Time offset option source tab in NSP module to reduce the gap between this dates. Please try to use it
