Force checking "Set time zone automatically using current location"

Hi all,

I'm having difficulties to force this check through a terminal command. Attached a screenshot.

In the end I want to push it to all computers through JAMF, but I can't seem to find the right command for it.

I found this one in several articles:
/usr/bin/defaults write /Library/Preferences/com.apple.timezone.auto Active -bool true

But it seems to be deprecated.

After that I found this one and tried it as well, but it doesn't seem to check the mark.
/usr/sbin/systemsetup -setusingnetworktime on

Therefore I'm wondering if there is an option to force it somehow?

I tried on Mojave and Catalina.

Best Regards and thank you,

The issue that ive been running into with this is by default it seem that location services are turned off to settings so this function is disabled. Maybe its the way ive setup prestage and DEP, but ive had to log in and do that manually.

I'm currently using this and seems to be working fine... note WiFi must be active...

#!/bin/bash

## enabling location services
/usr/bin/defaults write /var/db/locationd/Library/Preferences/ByHost/com.apple.locationd LocationServicesEnabled -int 1

uuid=$(/usr/sbin/system_profiler SPHardwareDataType | grep "Hardware UUID" | cut -c22-57)
/usr/bin/defaults write /var/db/locationd/Library/Preferences/ByHost/com.apple.locationd.$uuid LocationServicesEnabled -int 1

## configure automatic timezone
/usr/bin/defaults write /Library/Preferences/com.apple.timezone.auto Active -bool YES
/usr/bin/defaults write /private/var/db/timed/Library/Preferences/com.apple.timed.plist TMAutomaticTimeOnlyEnabled -bool YES
/usr/bin/defaults write /private/var/db/timed/Library/Preferences/com.apple.timed.plist TMAutomaticTimeZoneEnabled -bool YES
/usr/sbin/systemsetup -setusingnetworktime on
/usr/sbin/systemsetup -gettimezone
/usr/sbin/systemsetup -getnetworktimeserver

Immediately added this as a Self Service policy. Great stuff guys!

Hi,

I tried it on Catalina and it doesn't work.
Any ideas?

It works in Catalina. You could post the contents of your autotimezone.sh but the above code works just fine with a script and policy. In my example, I made it into a Self Service item, but you should be able to use other triggers. I have not tested on Mojave yet.

I can confirm this is no longer working in Catalina. It will do everything except for check the box: Set time zone automatically using current location.

This thread HERE talks about how it hasn't been working since 10.13.

100% works on 10.15.4. We are on Prem Jamf Pro.

@Dominic.Jaeckel In Terminal, if you first elevate to root and then execute your modified version of @larry_barrett's script, do you get different results than using sudo with your account?

@larry_barrett I think @tommillard is referencing the set time by Location rather than set network time. That being said, the above script does appear to work but a restart was required for it to be recognized on my test device.

@smpotter's script does require WIFI to be on. The autotimezone.sh script referenced above doesn't base your time on location, its a static location. Here's the JAMF code he's referencing:

# ABOUT THIS PROGRAM
#
# NAME
#   setTimeZone.sh -- Set the time zone
#
# SYNOPSIS
#   sudo setTimeZone.sh
#   sudo setTimeZone.sh <mountPoint> <computerName> <currentUsername> <timeZone>
#
#   If the $timeZone parameter is specified (parameter 4), this is the time sone that will be set.
#
#   If no parameter is specified for parameter 4, the hardcoded value in the script will be used.
#
# DESCRIPTION
#   This script sets the system time zone as reflected in the Date & Time preference pane with the
#   System Preferences application.  It has been designed to work on Mac OS X 10.3 and higher.
#
#   A list of supported time zone entries can be found by running the command:
#
#       For Mac OS X 10.5 or later:
#
#           /usr/sbin/systemsetup -listtimezones
#
#       For Mac OS X 10.4 or earlier:
#
#           /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Support/systemsetup -listtimezones
#
#   The system time zone will be set according to the value specified in the paramter $timeZone.
#   It can be used with a hardcoded value in the script, or read in as a parameter.  Since the
#   Casper Suite defines the first three parameters as (1) Mount Point, (2) Computer Name and
#   (3) username, we are using the forth parameter ($4) as the passable parameter.  If no parameter
#   is passed, then the hardcoded value will be used.

@andrew.nicholas is correct. I was speaking to the checkbox in the next one over. @larry_barrett your video shows what IS working, but the checkbox for this screenshot isn't working, which did before Catalina.

I'm probably not adding anything here but a data point, however I just tested @smpotter 's script via Self Service on a non-T2 chip MacBook Pro running macOS 10.15.4 and it worked fine (after reboot). Perhaps the T2 security chip is causing different behavior? I don't have a T2 Mac to test this on right now.

@macbrun I just tried running it and that checkbox does indeed become checked after a reboot. Thanks 🙂 This is on a T2 mac.

Hi,

sorry that I didn't reply anymore, but the script is working you just have to reboot after execution and the box is checked.

Works on Mojave and Catalina.

Best Regards,

Hello all, I'm trying to make this an "Available offline" self service item to help with some of my older MacBook Pros lose battery power totally and the time and date reset on them to like 2010, and wrong time etc. I tested it on a system and set the date back a year and it worked however when I set it to 2010, and tired to run it from self service which was no longer connecting to the JAMF server it fails. how does the make available offline checkbox work? I thought it would cache the policy locally

I used the following script tied to a launch dameon that ran every 10 mins to help with the same issue you are having. It is based on a script by @mm2270. If it can reach your ntp server, it does nothing. If it can't it will default to apple to set time. It helped alot with Macbooks that were left in drawers or off network fro a bit. we saw an added benefit for users that travel in that when the time zone changed, Outlook prompted them to update their Calendars and meetings
