Adjusting Time and Date

[R3ZNOR]

With the help of this site I have managed to get my new RPi 2 booted. All is great except the clock in the top righthand corner is 15m slow and the date is 2mths behind.

I have tried manually adjusting the date but it resets to 2mths ago. I can't see anywhere to adjust the time.

Any hints gratefully appreciated, thanks R3zn0r

If your timezone is off, it can be reset under "Internationalisation Options" in raspi-config. With Raspbian or Ubuntu, this command in a terminal will accomplish the same:

sudo dpkg-reconfigure tzdata

What is the output of the following terminal command?

ps -ef | grep ntpd

Open a command window
sudo /etc/init.d/ntp stop
sudo ntpd -q -g
sudo /etc/init.d/ntp start
exit

Great thanks for the responses. I will give them a try.

Open a command window
sudo /etc/init.d/ntp stop --> this stops the network time daemon which normally updates the time form the internet
sudo ntpd -q -g --> forces a time update from the internet
sudo /etc/init.d/ntp start --> restarts the network time daemon for automatic time updates
exit --> closes the terminal console

All this of course only works with an internet connection.
The time you see is the one that the kernel was compiled at. The Raspberry doesn't have a persistent hardware clock like a PC. It uses a fake hw clock which periodically saves the time to a file on the SD-card. It will default to the kernel compile time if no fake hardware clock data is available. At boot time if there is an internet connection available, it will set the timefrom there. If no internet is available it uses the fake hardware clock time, usually the time of the last shutdown, or the kernel compile time.
