argument date accepts the date and time in many formats. When the system boots, it has no concept of absolute time and will populate the system time with the date and time read from the hardware clock, thus to ensure that the time set using date is kept across reboots it has to be saved to the hardware clock.
While Debian prefer to keep the hardware clock in UTC (this prevents the need to change it on daylight savings and timezone changes) other systems (like Windows) by default keeps the hardware clock synchronized to local time.
It contacts NTP servers around the globe depend upon the configuration or you may configure NTP manually by editing default configuration file in /etc/file and NTP will fetch local time accordingly. Open terminal with “Ctrl Alt T” and type command ‘sudo apt-get install ntp’.
Update your packages list in case any error thrown as ‘Unable to locate package’ with ‘sudo apt-get update’ or please verify file at /etc/apt/ path.
I added the following line to $ date ; sudo service ntp stop ; sudo ntpdate -s gov ; sudo service ntp start ; date Thu Jan 1 UTC 1970 * Stopping NTP server ntpd [ OK ] * Starting NTP server [ OK ] Thu Feb 14 UTC 2013 notice the '-b' flag on ntpdate.
From ntpdate's man page: "Force the time to be stepped using the settimeofday() system call, rather than slewed (default) using the adjtime() system call.
The --set argument examples below is specified in the ISO 8601 standard's extended format as YYYY-MM-DD for Year-Month-Day Of Month, and time of day HH: MM: SS using 24 hour clock. To set the time automatically you need access to an NTP server.
Your local network may provide such a server but most people need to access an NTP server via the internet.Most Of My Servers runs on Open Source Platform called Linux.I want to have a terminal open and have something like a "repeating cat" command running in it for a certain text file (in particular /var/log/system.log).Since I had to do this earlier today, I decided it would make a lot of sense to write it down for the next time that I need to do it. First, you’ll need to install NTP if it isn’t already installed.For Debian or Ubuntu, that would be this command: You’ll find a lot of lines in there, but the important ones are the server lines.The "-g" option allows it to correct for time differences larger then 1000 sec.
