Change Linux Timezone

To check timezone in a Linux OS such as Ubuntu:


The output looks like this:

Local time: Fri 2020-04-10 15:10:28 AEST
Universal time: Fri 2020-04-10 05:10:28 UTC
RTC time: Fri 2020-04-10 05:10:29
Time zone: Australia/Perth (AEST, +1000)
System clock synchronized: yes
systemd-timesyncd.service active: yes
RTC in local TZ: no

For example, we need to change OS’s time zone from Australia/Perth to Australia/Sydney. Make sure the new timezone are supported by both OS and PHP. Check PHP supported Australia timezone here.

To find out a list of supported timezone in Ubuntu:

timedatectl list-timezones | grep -i australia

# Output timezones


To Change Ubuntu timezone:

# Firstly unlink current timezone

sudo unlink /etc/localtime

# Link new timezone with local time

sudo ln -s /usr/share/zoneinfo/Australia/Sydney /etc/localtime

Change PHP Timezone

Firstly, find out the current PHP version:

php -v

In our case it’s 7.1, then edit php.ini file used by Apache

pico /etc/php/7.1/apache2/php.ini

Un-comment line “;date.timezone =” change it to:

date.timezone = Australia/Sydney

Reload Apache 2

sudo systemctl reload apache2

Have a look at your access log to see if log time is the same as your local time, below is the default apache access log.

tail -f /var/log/apache2/access.log

It’s important to set up both PHP timezone and server OS timezone to your local time to ensure your website is running in the correct timezone. Also keep it in mind that, some third party modules can ignore your timezone settings and use UTC instead.
