Question

I want to change the time zone set in my Amazon EC2 instance running Ubuntu Linux to local time?

My Question

How to change the time zone in Amazon EC2?

Answer 1

UPDATED ANSWER FOR UBUNTU 16.04:

Do:

sudo timedatectl set-timezone America/New_York

to update your timezone.

To list down all the available timezones you can do:

timedatectl list-timezones

Answer 2

Another way of changing the time (This was done on an Amazon EC2 Linux instance)

Remove your localtime file

sudo rm /etc/localtime

Change Directory to ZoneInfo

cd /usr/share/zoneinfo

This folder contains all of the timezone information. You then just need to softlink to the appropriate zone.

Create a softlink to /etc/localtime

sudo ln -s /usr/share/zoneinfo/GB /etc/localtime

That will change your server timezone to GB

Answer 3

None of the above steps worked for me, so thought of writing this new answer here

# Delete any existing localtime link
sudo rm /etc/localtime
# Update time clock file with ZONE property
sudo vi /etc/sysconfig/clock
#Update the ZONE property to what you want say
ZONE="America/Los_Angeles"
sudo ln -sf /usr/share/zoneinfo/America/Los_Angeles /etc/localtime
sudo reboot

Answer 4

NOTE: This refers to a linux box (debian in my instance) should be used under your AWS launch configurations "User Data".

If you're planning to set the TIMEZONE on instance boot use below (works like a charm) use you're own Country/City instead of "Australia/Sydney".

#!/bin/bash

/bin/rm -f /etc/localtime; /bin/ln -s /usr/share/zoneinfo/Australia/Sydney /etc/localtime

Answer 5

Well described in below link

e:g- sudo timedatectl set-timezone Asia/Kolkata

Answer 6

Locate your timezone in the directory /usr/share/zoneinfo/.

E.g. To change timezone for Toronto /usr/share/zoneinfo/America/Toronto

Symlink your timezone to /etc/localtime e.g. for Toronto:

sudo ln -sf /usr/share/zoneinfo/America/Toronto /etc/localtime

Reboot to finish

reboot
