How do i change time zone settings?

I have a virtual machine that is set to PST that a couple of colleagues have in different time-zones.

If I wanted to change the time-zone to EST and GMT , what do I need to do?

Use timedatectl

sudo timedatectl set-timezone <timeszone>

---

Examples.

• Timezone as EST

  sudo timedatectl set-timezone EST
  

• Timezone as UTC

  sudo timedatectl set-timezone UTC
  

• Listing all valid Timezones

  timedatectl list-timezones
  

---

This command is perfect for automation scripts since it doesn't require any user interaction while compared to the other given answer based on dpkg-reconfigure tzdata .
