By default settings of elementary OS Freya, it only shows one time zone which was entered at the time of installation. But in these days where people travel long distances and often out of local time zone, it is a basic need for the PC to show time from different zones. This guide will walk you though the steps on how to setup multiple time zones in elementary OS Freya.
We will be using Dconf editor that activates several powerful features on your elementary OS.
Launch ‘Terminal’ and enter these commands one-at-a-time to install the Nautilus Dconf tools.
sudo apt-get update
sudo apt-get install nautilus dconf-tools
Go to ‘Applications’ and launch ‘dconf-editor’.
In the left pane of the dconf editor, go to ‘com>canonical>indicator>datetime’ and then in the right hand pane, check the boxes ‘show-calendar’, ‘show-clock’, and ‘show locations’. Finally double-click in ‘locations’ and add your preferred time zones separated by commas and with in single quotes.
You should immediately see the new time zones added to the clock.
