Thanks for feedback. Plus in disabled and all fine. It seems to be a conflict with the cache plug in WP Super Cache. After disabling this all is well. Deleting the cache did not solve the date issue but turning the Plug In off did.
Have re-activated and will see what happens.

I also just found this script in two WP instalations that both used the same Template. The Header file in each was hacked with the nemonn code.
Now removed from the header. All passwords noe changed and looking at Hardening.
