change timezone in zimbra


Changing the Time Zone in Linux

Before changing the time zone, you’ll need to find out the long name of the time zone you want to use. The time zone naming convention usually uses a “Region/City” format.

To view all available time zones, use the timedatectl command or list the files in the /usr/share/zoneinfo directory:

timedatectl list-timezones
...
America/Montserrat
America/Nassau
America/New_York
America/Nipigon
America/Nome
America/Noronha
...

Once you identify which time zone is accurate to your location, run the following command as root or sudo user:

sudo timedatectl set-timezone <your_time_zone>

For example, to change the system’s timezone to America/New_York you would type:

sudo timedatectl set-timezone America/New_York
sudo timedatectl set-timezone Asia/Kolkata

To verify the change, invoke the timedatectl command again:

timedatectl
                      Local time: Tue 2019-12-03 13:55:09 EST
                  Universal time: Tue 2019-12-03 18:55:09 UTC
                        RTC time: Tue 2019-12-03 18:02:16
                       Time zone: America/New_York (EST, -0500)
       System clock synchronized: no
systemd-timesyncd.service active: yes
                 RTC in local TZ: no

Mission accomplished! You’ve successfully changed your system’s time zone.
