Thanks jggimi I had already gone through the mailing list and read that thread. I have added localtime (/usr/share/zoneinfo/Europe/Dublin) to /var/www/etc/localtime and tested using :
Code:
$ cp /bin/date /var/www/bin
$ chroot /var/www /bin/date
It reported the date fine and in IST. It's starting to really really annoy me now :S
I'll try speaking with the maintainer of nfdump to see if they have had any similar issues.
