I did a clean install of Ubuntu 18.04 LTS on my laptop a couple of days back. During installation, I chose the timezone to be my local time zone i.e., Kolkata, India (Indian Standard Time). However, after booting my system, the time and date are showing incorrect values.
date: Sat Aug 10 2019 time: 22:16:xx
Actual values at that time:
date: Sat Aug 10 2019 time: 11:16:xx
Precisely, the displayed time is 11 hours ahead of the actual time.
In Settings --> Date and Time, the Automatic Date and Time, and the Automatic Time Zones switches are also enabled.
I found some articles on the internet using which I tried to analyze/fix the issue (Screenshots attached).
sudo ntpq -p
sudo nmap -p123 -sU -P0 localhost. I think it checks the status of UDP port 123.
What should be the next steps I need to perform to fix this issue?
