One of our customers has locations in the Netherlands, China, and the US. They are using Intune and wanted the timezone to be configured automatically for their users; setting a default one was not an option because they could be in different time zones in the US. In this blog post, I will show you how to configure that once using the Script option or as a Remediation.
Limitations
When you deploy the script, you could run into these limitations:
- The timezone will be set based on the device’s public IP at the time of deployment or whenever the remediation script runs. If the device is VPN-connected using a full tunnel instead of a split tunnel configuration, the timezone may not be what you expect. Depending on its registration, the internet provider’s public IP may also put you in another timezone.
- I viewed and tried other examples of retrieving the timezone using Azure Maps. That also works but allows only 5K monthly requests on the free tier. The script uses the free ident.me service, and perhaps this is something your company policy might not allow.
How does the script work?
I created two scripts that can be used in Intune. One only sets the timezone once using the Scripts pane under the Devices pane. The other is a remediation detection script that will detect the current location and time zone and compare it to the one configured on the Windows device. If it differs, it will run the first script and configure the Windows timezone accordingly.
The script uses the ident.me website (Thanks Stephan van Rooij for pointing out that free to use website, i previously used one that allowed 50K free requests per month) to detect the current location of the Windows device based on the public IP information. The site will return details, including the IANA (Internet Assigned Numbers Authority) timezone name of the location found. (Europe/Amsterdam, for example). The script uses that to configure the matching Windows timezone name by looking it up in a PSCustomObject table, which is included in the script.
If the ident.me website can’t be reached, the Detection script will report that in the logs; it will try again later and return the Exit 0 code. The reason is that if the site ident.me can’t be reached, the Remediation script will also not be able to reach it and can remediate the timezone at that moment.
Example output when using the ident.me website: (I changed the values for privacy reasons 😉 )
ip : 123.123.123.123 aso : Fiber Company asn : 123456 continent : EU cc : NL country : The Netherlands city : Where I live postal : 1234 latitude : 54.321012 longitude : 5.123456 tz : Europe/Amsterdam
Deploying the script in Intune
Using it as a one-time script
Below are the steps for adding the script to Intune and letting it run once for the device:
- Go to the Scripts pane in Intune Devices – Microsoft Intune admin center.
- Select Add
- Select Windows 10 and later
- Enter a Name (Timezone configuration, for example.)
- Enter a Description (Automatic timezone configuration using ident.me, for example)
- Select Next
- Click on Select a file and browse to the script that you copied from this page.
- Change the Run this script using the logged on credentials value to No (It must run as System)
- Change the Enforce script signature check to No
- Leave the Run script in 64 bit PowerShell Host to its default value of No
- Select Next
- Configure a Scope Tag if needed and select Next.
- Select Add groups, and assign it to the group(s) containing the devices.
- Select Next and review the settings.
- Select Add to add the script to Intune.
Using it as a Remediation
Below are the steps for adding the scripts to Intune as a Remediation: (You can only use the scripts as a Remediation with the correct licensing)
- Go to the Remediation pane in Intune Devices – Microsoft Intune admin center
- Select Create script package
- Enter a Name (Timezone configuration, for example.)
- Enter a Description (Automatic timezone configuration using ident.me, for example)
- Enter a Publisher (PowerShellisfun, for example)
- Select Next
- Click on Select a file for the Detection script file and browse to the detection script you copied from this page.
- Click on Select a file for the Remediation script file and browse to the remediation script you copied from this page.
- Leave the settings values to No for the Run this script using the logged-on credentials, Enforce script signature, and Run script in 64-bit PowerShell.
- Select Next
- Configure a Scope Tag if needed and select Next.
- Select Select groups to include, and assign it to the group(s) containing the devices.
- After adding the group(s), it will run daily by default at 1:00:00 AM every day for each group. You can change it by clicking on Daily and changing the time to 12:00:00 PM, for example, or to hourly with a repetition of X hours.
- Select Next and review the settings.
- Select Create to add the custom remediation script to Intune.
Example
In the example below, I deploy a VM to my tenant. During deployment, the timezone is configured to Pacific Standard Time… After deployment, it’s configured to the correct timezone (Which is W. Europe Standard Time, in my case, because I live in the Netherlands)
Before Autopilot deployment:
After Autopilot deployment:
Wrapping up
In the chapters above, I showed you how the script works, how to add it to Intune, and the limitations. We tried to solve the timezone setting initially using Location Services, which didn’t work. This script works and is easy to implement for existing Intune clients and new Autopilot devices. You could also deploy using both methods; by doing so, the time is configured correctly during deployment, and afterward, it will be remediated if the user moves to another location.
The scripts
Below are the remediation and detection scripts for Intune. Save them somewhere and use them in Intune. And yes, they are long because of the timezone table, which I use to convert the IANA naming (Left side) to the Windows timezone setting. (Right side).

Thx Harm! This remediation saved me a lot of time. To get the remediation script up and running i have to change line 469 from Set-TimeZone -Name $timezone.Value to Set-TimeZone -Id $timezone.Value
I will check that out now myself, did do a change in time provider service and perhaps I didn’t change that 😕
I thought it was a PowerShell 5.1/7.4 issue, but I tested both. Windows 10 and 11 also… Could you give me some details on the devices you’re using? And they timezone you’re in?
The Name parameter of Set-TimeZone must match the StandardName or DaylightName properties of the TimeZoneInfo object. I think this names depends on your OS language.

The Id parameter should always be the same, no matter which language your OS is
Yes, the language setting and Name parameter is not the best solution 🙁 Changed the blog post to use the Id parameter after testing. Thanks for the feedback!
Hi, nice scripts! Let me add the importance of error handling, if the rest query to the ‘https://ident.me/json’ fails, the detection script shall rather exit with 0 and write-output like ‘there was an error getting location specific information from https://ident.me/json, will not run remediation this time!’
Thanks, changed it to a try / catch for the Detection script. Didn’t add that to the Remediation script, because if the Detection works for the ident.me website… The Remediation should also work 😉
thanks. great post. i was looking for one-off script. do you have it? does not saw in your github. when run one-off script during pre-provisioning, after the user login in, it won’t change back to default?
You could use the remediation script for that, not sure what will happen after the user logs in… Let me know if you can test that 😊
the worst tutorial I evere seen
Could you explain what you are missing in this blog post?
Thank you for the remediation, this is a perfect solution for our environment. In our environment tztautoupdate did not work consistently.
There is one little bug in your script which is easily fixed. We have users in Ukraine, and the script still refers to the Russian translation of the capitol:
“Europe/Kiev”
This gives an error, it needs to be:
“Europe/Kyiv”
I think the table is correct, but it’s in English and not sure what your operating system language is? You can adjust it to your needs, of course
Hi Harm,
Luckily I found an old out in the Remediation script. When the table still was “Europe/Kiev”, I got the following as output of the detection script:
The currently configured timezone FLE Standard Time doesn’t match the timezone Europe/Kyiv which was being matched by the clients IP Location
Then the remediation started, and failed with the following error:
Set-TimeZone : Cannot bind argument to parameter ‘Id’ because it is null. At C:\Windows\IMECache\HealthScripts\380aa215-e9bc-4eb7-93af-35ae2a3feccc_3\remediate.ps1:485 char:26 + Set-TimeZone -Id $timezone.Value + ~~~~~~~~~~~~~~~ + CategoryInfo : InvalidData: (:) [Set-TimeZone], ParameterBindingValidationException + FullyQualifiedErrorId : ParameterArgumentValidationErrorNullNotAllowed,Microsoft.PowerShell.Commands.SetTimeZone Command
It could not match a value found in your table, because it was looking for “Europe/Kyiv”. After changing the detection and remediation script with the new values, the script ran without error.
The devices in Ukraine are installed with an en-us (clean) image.
That’s strange, I will update the table on the blog post!
And updated GitHub, too 🙂 Thanks for mentioning this!
