The zone's signatures are weird:
$ unbound-host -f /usr/local/etc/unbound/root.key -v www.wilda.nsec.0skar.cz
validation failure <www.wilda.nsec.0skar.cz. A IN>: signature inception after expiration from 2001:1528:132:70::1 for key nsec.0skar.cz. while building chain of trust
$ dig +noall +ans +nocl +nottl +nosplit +cd +dnssec -t a www.wilda.nsec.0skar.cz
www.wilda.nsec.0skar.cz. CNAME flexi.oskarcz.net.

Note the RRSIG dates for the CNAME:
Perhaps unbound is comparing these as 32-bit timestamps. Just
under 66 years is an impressive validity range, if intentional.
