T_DATE_IN_FUTURE_96_Q

I am getting my own emails tagged with T_DATE_IN_FUTURE_96_Q but eg a gmail message is not tagged like this. Everything in here is ntp synchronised and configure on CET time. At first I thought time zone in the spassassin container was not ok but changing the container with this did not fix this. 

apk add tzdata --no-cache
cp /usr/share/zoneinfo/Europe/Warsaw /etc/localtime 
echo "Europe/Warsaw" > /etc/timezone

Has anyone else this? How is this T_DATE_IN_FUTURE_96_Q computed? I have the impression this has maybe something to do with incorrect date / timezone detection inside a container.
