Unbound performs serial arithmatic on the timestamps in the rrsig, 
according to RFC. 

(What does that mean? The timestamps are 32bit in the RRSIG, but the 
value is interpreted relative to the current date. And what you cannot 
do is express something like a point more than some number of years 
future or past.)

Hello Wouter,



Thanks for the insight. Maybe this has something to with the platform?

 CentOS 6.9:

  $ unbound-host -v -f /etc/unbound/root.key -t A www.wilda.nsec.0skar.cz

  www.wilda.nsec.0skar.cz is an alias for flexi.oskarcz.net. (secure)

  flexi.oskarcz.net has address 85.239.227.179 (secure)



MacOS 10.13.2 (High Sierra):

  $ unbound-host -v -t A -f /usr/local/etc/unbound/root.key 
www.wilda.nsec.0skar.cz

  www.wilda.nsec.0skar.cz is an alias for flexi.oskarcz.net. (BOGUS (security 
failure))

  flexi.oskarcz.net has address 85.239.227.179 (BOGUS (security failure))

  validation failure <www.wilda.nsec.0skar.cz. A IN>: signature inception after 
expiration from 85.239.227.179 for key nsec.0skar.cz. while building chain of 
trust



FreeBSD 11.1:

  $ unbound-host -v -f /usr/local/etc/unbound/root.key -t A 
www.wilda.nsec.0skar.cz

  www.wilda.nsec.0skar.cz is an alias for flexi.oskarcz.net. (BOGUS (security 
failure))

  flexi.oskarcz.net has address 85.239.227.179 (BOGUS (security failure))

  validation failure <www.wilda.nsec.0skar.cz. A IN>: signature inception after
