Displaying post dates as 10 years into the future. ie. from 2021.

Hi everyone,

I’m writing a science fiction blog set 10 years into the future.
I basically need all posts to display as if they are 10 years from now.

Eg. It posts needs to display as:
February 7, 2021 instead of
February 7, 2011

And next year need it to display as 2022 instead of 2012 etc.

This will be for every post that I write.
How can I automatically add 10 years to every post date?

I realise it’s a bit of an odd request, but it’s necessary for this particular project. I know it’s possible – Just not sure how.

PS. I’m familiar with the ‘No Future Posts’ plugin, http://wordpress.org/extend/plugins/no-future-posts/ which allows you to date posts in the future and have them display as that future date but it means that I then can’t schedule posts, and I still would like to be able to schedule posts aswell.

I hope someone out there can help. It would be very much appreciated.

thanks
Luke
