Date and time settings in Debian Linux
Set date and time approximately (optional step):
$ sudo su
# apt-get install ntpdate
# ntpdate ntp.cesnet.cz
Install NTP for higher precission with automatic time synchronization:
# apt-get install ntp ntp-server ntp-simple ntp-doc
Configure NTP for automatic time synchronization:
Open file /etc/ntp.conf
Add lines:
server clock1.zcu.cz
server clock2.zcu.cz
server ntp.cesnet.cz
Comment out everything except following directives:
driftfile, statsdir, statistics, filegen (more lines in sequence)
Start NTP server:
# /etc/init.d/ntp-server restart
Display current time settings:
# ntpq -p
- shows table of servers accessibility and accuracy
- main server is marked by star (*), else automatic synchronization does not work
Store date and time to hardware clock:
# /usr/sbin/ntpdate -s
# /sbin/hwclock --adjust
# /sbin/hwclock --systohc
