Time / Timezone in Linux
Before set timezone you should delete the current settings if they exists: Create backup
cp /etc/localtime /etc/localtime.bcp
Delete current settings
rm /etc/localtime
Set new Timzone, for example:
ln -s /usr/share/zoneinfo/CET /etc/localtime
Check Date/Time:
date
If you see that date/time is incorrect you should sync it using ntpd service. Sure you can set it manually. If ntpd service not installed install it using yum or apt-get. NOTE that you can't use ntpd from ovz container.In general you can only change timzone from ovz container
Start ntdp:
service ntpd start
force sync:
ntpdate pool.ntp.org
Also you can configure ntpd servers in /etc/ntp.conf. for example add next line to conf:
server pool.ntp.org
Here is examples how to set time/date manually:
date --set="23 Nov 2013 11:00:00" date --set="11:00:00"
