Setting Tanggal dan Jam di Linux

To have the correct time and date in Linux is very important, a lot of things depends on it. It does not matter if you are using Linux to power your personal computer or you have a Linux server. The server and system clock needs to be on time.
Set date from the command line
date +%Y%m%d -s "20120418"
Set time from the command line
date +%T -s "11:14:00"
Set time and date from the command line
date -s "19 APR 2012 11:14:00"
Linux check date from command line
Will show you something like this:
Thu Apr 19 15:17:34 BOT 2012
Set hardware clock
The hardware clock is the clock that runs in you PC hardware even if you disconnect it from the main power supply. This is because it has a lithium battery in the modern computers and another type of battery in the old ones.
We'll see differences between hardware clock and system clock
hwclock --show
Will output something like this:
Thu 19 Apr 2012 03:23:05 PM BOT  -0.785086 seconds
Now check the system clock
Will output something like this:
Thu Apr 19 15:26:41 BOT 2012
Let's set the hardware clock to local time:
hwclock --set --date="2012-04-19 16:45:05" --localtime
If you want to set it to UTC time use:
hwclock --set --date="2011-04-19 20:45:05"  --utc
Set the timezone
To set the timezone of your system clock do the following:
cp /usr/share/zoneinfo/America/La_Paz /etc/localtime
Choose the right timezone for you.
Automatically adjust your computer clock
To have your system to automatically adjust time we need to install ntp. Get it from your repository. Once installed you can configure it this way:
Edit the file /etc/ntpd.conf. It will look like this:
# With the default settings below, ntpd will only synchronize your clock.
# For details, see:
# - the ntp.conf man page
# - http://support.ntp.org/bin/view/Support/GettingStarted
# - https://wiki.archlinux.org/index.php/Network_Time_Protocol_daemon

# Associate to public NTP pool servers; see http://www.pool.ntp.org/
server 0.pool.ntp.org
server 1.pool.ntp.org
server 2.pool.ntp.org

# Only allow read-only access from localhost
restrict default noquery nopeer
restrict ::1

# Location of drift and log files
driftfile /var/lib/ntp/ntp.drift
logfile /var/log/ntp.log

# NOTE: If you run dhcpcd and have lines like 'restrict' and 'fudge' appearing
# here, be sure to add '-Y -N' to the dhcpcd_ethX variables in /etc/conf.d/net
Be sure to start the daemon, and to make it start automatically when the system boots.
On Arch Linux is: /etc/rc.d/ntpd start on Debian and derivatives /etc/init.d/ntpd start
Update from the command line against a time server
You can update the clock manually, without the need of the daemon with ntpdate
You will get something like this:
19 Apr 15:45:23 ntpdate[10948]: step time server offset -45.697084 sec
Bonus: Set the time and Date on Gnome
If you are using Gnome right click on the clock and select adjust, or go to: System > Administration > Time and Date (You may be asked for root password)
You will see a window similar to this one:
Ubuntu gnome time and date
