How to generate expiring SSH Key ?

Hi Gurus,

I am stuck with a problem here for which I need your expert advice.
I need to generate an SSH key in my Sun OS machine which should expire in 2 years. I usually generate the keys using ssh-keygen -t dsa but the keys generated like this would be non-expiring.

I checked for the man pages for ssh-keygen but could not find an option for expiring the key. Another option I could find was to use ssh-add -t xh option which will expire the key in x hrs. Is this the route I should take ? I want to confirm this first since I need to do this in production environment.

Thanks,
Sabari Nath S
