Check Current Timezone
Using these commands we can see the current date & time:
1. Using date command:
Tue Jan 28 16:09:48 +06 20202. Using ls -l /etc/localtime command:
lrwxrwxrwx 1 root root 32 Jan 27 15:44 /etc/localtime -> ../usr/share/zoneinfo/Asia/Dhaka3. Using timedatectl command:
Local time: Tue 2020-01-28 16:21:31 +06
Universal time: Tue 2020-01-28 10:21:31 UTC
RTC time: Tue 2020-01-28 10:21:31
Time zone: Asia/Dhaka (+06, +0600)
System clock synchronized: no
NTP service: n/a
RTC in local TZ: noAvailable Timezones
To see available time zones, we need to run command like:
# all timezones
timedatectl list-timezones
# timezones of Asia
timedatectl list-timezones | grep Asia
You’ll see the output like:
......
Asia/Dhaka
Asia/Dili
Asia/Dubai
Asia/Dushanbe
Asia/Famagusta
Asia/Gaza
......Change Timezone
The syntax of changing timezone command is:
sudo timedatectl set-timezone your_timezoneSelect your timezone from the list. To set Asia/Dhaka, run this command:
sudo timedatectl set-timezone Asia/DhakaStep 4 : Change Timezone Using Symlink
If your server doesn’t work timedatectl command, then follow this method. We need to delete localtime first:
sudo rm -rf /etc/localtimeThen set the timezone like this:
sudo ln -s /usr/share/zoneinfo/Asia/Dhaka /etc/localtimeNow check the timezone.
