Well, when the intention is just experimenting and testing Knot behavior during roll-overs, then such settings is pretty much OK :)

For real DNSSEC deployment, there is no reason to have key lifetime shorter than several months.

I have the following signing policy configured in a test environment:

These settings are insane. You shouldn't have that short lifetime for
ksk. Make sure your ksk lifetime is at least multiple times longer than
zsk lifetime.
