Why time changes itself?

Why does time change by itself? delay of time by 51 minutes. yes,automatic time is on.

Something that would help us a lot to understand the problem would be this:

  1. Open the application called ‘Terminal’
  2. In this application run the command:

eos-diagnostics

  1. The above command will create a file with the information of your system (example: eos-diagnostic-160614_111731_UTC + 0100.txt); Send us this file so we can analyze and see a possible solution

eos-diagnostic-210206_153847_UTC 0530.txt (7.0 MB)

Update for Endless OS 3.9.2 by APP Center

Can you please post the output of:

sudo systemctl status fake-hwclock.service

OK, seems good so far. Can you please run the following command and upload the generated file ntp.txt from your home directory here.

journalctl -u ntp.service 2>&1 1>~/ntp.txt

ntp.txt (102 Bytes)

For some odd reason, the NTP service which is responsible for keeping your computers time in sync seems not running. Can you please enable it with:

sudo systemctl enable ntp.service
sudo systemctl start ntp.service

Does this throw any errors? If it does, can you please post the output of:

sudo systemctl status ntp.service

thank you.
time updated to current time with commands you gave.

now,

  1. why did this happen?
  2. another problem still persists Admin Setting missing

seems something seriously wrong with updates lately
