Timezone problem

Hello everyone, We've just started to test NAV and I have a strange problem with the timezone reported in NAV. It seems that NAV reports all operations using timezone GMT+1 (Western Europe) but on localhost we have configured a different timezone: diff -s /etc/localtime /usr/share/zoneinfo/`cat /etc/timezone` Files /etc/localtime and /usr/share/zoneinfo/America/Chicago are identical We are using Debian Squeeze 64-bit and NAV 3.10 installed from source. What am I missing? Regards, Adrian
