I always have some time issues in Linux. Here the howto:
Check the time
# date Fri Mar 18 21:50:43 CET 2011
Install and configure NTP
# yum install ntp # service ntpd stop # ntpdate pool.ntp.org # /etc/init.d/ntpd start # chkconfig ntpd on
Configure the localtime
# cd /etc/ # ls -la |grep localtime # /etc/localtime -> /usr/share/zoneinfo/Europe/Amsterdam # ln -sf /usr/share/zoneinfo/Europe/Amsterdam /etc/localtime
Configure the shell time
export TZ=CET
