How to set time and date on Raspberry PI automatically when turned on from NTP server? I tried to do as described here - roberthanson1.wordpress.com/2013/03/23/day-5-getti...
Installed servers in ntp.conf in ru.pool.ntp.org - did not help, the date is still incorrect .

Answer 1

The raspberry pi does not have a hardware clock:

[email protected]:~ $ sudo hwclock 
hwclock: Cannot access the Hardware Clock via any known method.

Therefore, we go the other way:

[email protected]:~ $ date
Wed 15 Feb 08:00:59 UTC 2017

[email protected]:~ $ sudo dpkg-reconfigure tzdata 
Current default time zone: 'Europe/Moscow'
Local time is now:      Wed Feb 15 11:15:58 MSK 2017.
Universal Time is now:  Wed Feb 15 08:15:58 UTC 2017.

[email protected]:~ $ date 
Wed 15 Feb 11:16:08 MSK 2017

[email protected]:~ $ sudo ntpdate -u ntp.ubuntu.com
15 Feb 11:16:39 ntpdate[7529]: adjust time server 91.189.94.4 offset -0.001106 sec

[email protected]:~ $ date 
Wed 15 Feb 11:16:49 MSK 2017

*May require "ntpdate" to be installed (aptitude install ntpdate).
It is possible without it, check the existence of the /etc/ntp.conf file

[email protected]:~ $ sudo /etc/init.d/ntp restart
[email protected]:~ $ sudo ntpd -gq

From the raspberrypi forum to the topic NTP / time settings
PS It is quite correct to recommend using sudo raspi-config in the menu, select Localization Options-->Change Timezone-->...
Or if you are a geek, you can also work with your hands poke and poke .

Answer 2

The link in the comments says that if the date differs by more than 1000 seconds, the time will not be synchronized automatically. Maybe your case?
