It is, actually. https://manpages.ubuntu.com/manpages/xenial/man1/ssh-keygen.1.html https://manpages.ubuntu.com/manpages/xenial/man1/ssh-keygen.... look for "-V validity_interval". Admittedly that's on the certificate rather than the key itself (yes, SSH keys can have proper CA infrastructure!) and not something most people have to worry about.

That's pretty clearly what GP was referring to. And I completely understand how annoying it would be, too. Consider this, you might not even use it again before it expires again, but if you don't re-add it promptly you probably won't be able to figure out why stuff isn't working the next time you do use it...
