Creating a field in Skills and Qualifications that populates automatically with a future date?

Hi all,

For our client we need to create an automatism on the page of skills and qualifications: an expiration date field will have to be filled automatically (for example the field "Expiration date" will have to populate automatically with the corresponding date in 10 years)?
How can we handle this request?

Someone has some idea?

Thanks,

Anamaria
