Configuring the timezone on TurnKey Linux

For some TurnKey appliances, it's important to set the date and time of the server before starting to use the application.


  • We're installing a blog or forum application, and we want to know the exact date and hour a blog post was made.
  • We're installing an issue tracker, and we need to to know the exact date and time when an issue was created or closed.
  • We're installing a database, and it's important for us to be able to audit the database. The date and time should be correctly configured and reflected on the database logs. 

When you deploy a TurnKey appliance, it comes with UTC timezone configured by default, from which the rest of timezones are calculated. To configure our own timezone, you use one of two methods.

1) Setting timezone using Web interface (webmin)

By default, Turnkeylinux doesn't come with webmin's system time module. Here is how you can install it and use it to change your timezone:

1. Access webmin using your prefered browser at https://your-appliance-ip:12321 and login as root with the password you stablished at installation time.


2. Navigate from the main menu to System->Software Packages, and in the section Install a New Package, we select Package from APT and write "webmin-time" as the name of the package. Click on the install button.


3. Once the module is installed correctly, we follow the "Return to module index" link. Now, we'll have available the System Time option in the System menu.


4. Access the System Time option, and select Change Timezone. There you'll be able to select your timezone and apply it, and the server will change the time and date to correspond with your setting. 



2) Changing timezone via Command Line Interface

If you are confortable working at the CLI level, follow this procedure:

1. SSH to your server as root, using the password you stablished at installation time.

2. Run the command "dpkg-reconfigure tzdata". You'll be able to select your timezone and the system will configure time and date accordly.


That's all, now you will have your server ready for use, with the correct time and date reflected!

Is there anything this doesn't solve? Not so far.

It would be great if it were part of the default distribution.

It is...and easier to run from the command line to boot!

But I think that there is a case for setting time as well as keyboard on install/firstboot. Perhaps we need to start a poll about it and see what everyone reckons? Actually I've just created a poll. Please go and vote! :)

  Thanks for providing the command to set the time zone using the Command Line Interface.

  Is there to set it without going through the interface menus?

  In my procedure, I want to set it to Brisbane/Australia.  Can I set this as a parameter?

I haven't tested this (simply just robbed it form here and adjusted it to suit).

echo $TIMEZONE > /etc/timezone
cp /usr/share/zoneinfo/${TIMEZONE} /etc/localtime # This sets the time

It seems to be because the originals are hosted on Adrian's blog, which he has updated. I have emailed the devs in the hope that they will fix it soon, but in the meantime have a look at Adrian's original blog post here (it's in Spanish so you'll need to use Google translate or similar if you can't read Spanish).

[update] That was quick! It's fixed now! :)

and how to change the keyboard ... ?

I have set the time sync in webmin about every 10 minutes

Something is doing a time change even faster and is aplying a time-change adding 30 minutes

Current default time zone: 'Europe/Amsterdam'
Local time is now:      Wed Aug  7 18:53:04 CEST 2013.
Universal Time is now:  Wed Aug  7 16:53:04 UTC 2013.

root@otrs /var/log# date
Wed Aug  7 18:23:31 CEST 2013
root@otrs /var/log# date
Wed Aug  7 18:23:49 CEST 2013
root@otrs /var/log# date
Wed Aug  7 18:54:56 CEST 2013
root@otrs /var/log# date
Wed Aug  7 18:57:20 CEST 2013
root@otrs /var/log# date
Wed Aug  7 18:28:29 CEST 2013

This is resulting in verry strange tickets.

Can somebody tell me how to find out wich process is changing my system time?

(Turnkey-otrs 2.4.7 default server)

If so perhaps check your BIOS time. It should be configured for UTC. Beyond that I wouldn't even know where to start sorry. Although perhaps disable the auto time update and then manually change the time and see what happens... Perhaps also check cron for other time keeping processes that may be running... I'm only guessing though really...

I was monitoring the time-changes with top, I'm guessing the vmware-tools process is influencing the time aswell. I keep you posted.

We are experiencing the same problem on a VMWare host as Zandweter.

Even though we have an NTP time source set to check once a day, the time always seems to be about 15 minutes fast.

How does one get the server back to the correct time?

Using step 2, 2.  dpkg-reconfigure tzdata

How would I configure the time server or when and how often to perform time sync in CLI?
