if i transfer domain to other registrar

[admin]

I have a question, and i actually don't know the answer to it, which is odd.

Say a domain has 1 year left before it expires. What happens if you transfer that domain from lets say godaddy to namecheap. Will the transfer add another year ontop of that? Or make it just expire one year from the date of the transfer?

I always thought it was the latter, but i'm actually not too sure.

thanks.
