I am trying to boot from USB and sync time using "ntpdate" command from a windows PC as ntp server.

OS : Lubuntu live usb

when i run the ntpdate command it is getting executed and the date is set properly but the time is not getting synced.

So my question is that whether is it possible to set the time using ntpdate command after booting from a USB? If yes then, what i need to do? If no then, why?

it seems that ntpdate is depreciated try:

sudo service ntp stop
sudo ntpd -gq
sudo service ntp start

OUTPUT:

{~}:$ sudo service ntp stop
{~}:$ sudo ntpd -gq

See if this will do what you need. Also .. .ntpdate will not be able to connect if the service is running .. so you may be able to use

sudo service ntp stop
sudo ntpdate -s us.pool.ntp.org
sudo service ntp start

OUTPUT:

{~}:$ sudo service ntp stop
{~}:$ sudo ntpdate -s us.pool.ntp.org
{~}:$ 

But I tried this and didn't seem to get any output like I did with the ntpd -gq command.

  • I tried this but after that the ntpdate is updating date but time is still not getting updated. – Anivesh Pandeya Jun 1 '16 at 12:49
