I'm unable to change the current date in Windows Sandbox. I have disabled "Set time automatically" from the settings panel and I'm able to change the date, but 1 or 2 seconds later the date reverts to the current one.

This seems to be an issue similar to Changing Windows 10 System Clock Doesn't Work but I don't know how to disable time synchronization for Win Sandbox.

Does anyone have any idea about how to keep this from happening?

Running

OS Name:                   Microsoft Windows 10 Pro for Workstations
OS Version:                10.0.19041 N/A Build 19041

Picture of my date/time settings. enter image description here

Misc:

  • The windows time service is already disabled

  • This is expected behaviour, as it is working off of Hyper-V, and the Guest Additions are installed/activated automatically in Windows Sandbox.

  • Disable svc Hyper-V Time Synchronization Service inside the sandbox. See this answer.

A bit late to the party, but I just stumbled upon this..
All you have to do is disable Hyper-V Time Synchronization Service inside the sandbox.

This is not the perfect answer to this problem, But if you want to run software on a different date and time you can use RunAsDate application. This app is allowing you to run a specific software at different times and date and it works great on Windows Sandbox. http://www.nirsoft.net/utils/run_as_date.html

You need stop (and possibly disable) the Windows Time services from the Windows Services manager.

Start > run > services.msc

Look for Windows Time

Right-click and Stop or right-click and go to Properties, then change the Startup type to disabled.

  • Looked it up and that's not the solution in my case, Windows Time is already disabled.

Very crude, but seems to work. Copy/paste into Powershell ISE

for ($num=1; $num -lt 9999999999; $num++){ sleep -Milliseconds 500 set-date 12/22/21 }

Adjust timing as needed.

Building on Jony Adamit's answer: Create the text file below on the host (extension: .wsb), then double-click to launch the Sandbox.

no_time_sync.wsb

<Configuration>
  <LogonCommand>
    <Command>net stop "Hyper-V Time Synchronization Service"</Command>
  </LogonCommand>
</Configuration>
