How to fix wrong system time and date?

I just ran a clean install of 12.10 on my sys76 laptop.

Time and date reads: 19:36 31 december 1969, even though it is: 13:29 07 november 2012.

I have it set for my location and it won't change manually, even tried in the command line with tz.

I think it is messing up the security certificates over the Internet cause I cannot change PPA over command line and going to Launchpad brings up the certificates page in Firefox.

Is this some known bug or is there a fix for it?

Try:

sudo ntpdate ntp.ubuntu.com

Yes, it would certainly mess with the SSL certificates, because they would be future-dated.

I doubt it's a bug in Ubuntu. Your CMOS clock in the BIOS must have been set to that somehow.

Just install ntp server:

sudo apt-get install ntp

It will automatically keep your clock synchronized.

Install ntp and ntpdate executing the following commands-

sudo apt-get install ntp
sudo apt-get install ntpdate

Then, execute

sudo ntpdate ntp.ubuntu.com

This works for me.

After installing 12.10 I had the same problem as well. Somehow the new installation set the BIOS clock to the year 2070 !! After this, Ubuntu wasn't able to set a different date both by ntp, manually, even using the date command.

Setting the right date in the BIOS settings solved the problem.

This works for Ubuntu 16.04

1. Stop the ntp service

2. Run ntpdate command to fetch date/time from ntp.ubuntu.com

   systemctl stop ntp
   sudo ntpdate -s ntp.ubuntu.com

P.S: Make sure ntp is installed, if not just do

sudo apt-get install ntp

I changed the hardware clock. Use the hwclock command to fix it:

sudo ntpdate <my.ntp.server>
sudo hwclock -w
