Milter-greylist

Hello,

I'm a newby to this group and using 4.4.3 I'm getting negative numbers like 

Jul 11 10:33:50 mailer milter-greylist: created: AUTO 1.2.3.83 from <newsletter@sender> to <tony@...> valid for 23:13:37

Jul 11 10:33:50 mailer milter-greylist: created:  1.2.3.82 from <danielle@sender> to <heskelt@example.com> delayed for -119:-47:-31

when kilter-greylist restarts. The AUTO (whitelisted) entries seems to be o.k. but the greylisted are with random negative numbers. In my greylist.conf I'm using 8m for delay, which is definitely not seen with these numbers.

Anyone here with a tip what happens?
