How to set system time in Windows 10 IoT?

Question

Is there a way to set system time from my app running on a Raspberry Pi 2 in Windows 10 IoT Core Insider Preview?

This doesn\'t work for lack of kernel32.dll

Answer 1

You can call any PowerShell routine from C# on UWP/IoT-Core systems. As such, the PowerShell commands are always available in/to your App.

For an example, see the ProcessLauncher sample on GitHub.

ALTERNATIVE, schedule a startup PS script as follows:

Run PowerShell as an Administrator on the board (Press the Windows button, and start typing PowerShell, right click on the icon and select “Run as Administrator”).

Set-ExecutionPolicy RemoteSigned

PuTTy to RPi as admin and:

setx PATH "%PATH%;C:\Windows\System32"

schtasks /create /tn "StartupPowerShell" /tr c:\Startup.bat /sc onstart /ru SYSTEM

Startup.bat

powershell -command "C:\IotCoreStartup.ps1"

IotCoreStartup.ps

$logFile = 'C:\StartupLog.txt'

get-date > $logFile

tzutil /s "UTC" >> $logFile

# set alternate time servers
"Setting additional time servers" >> $logFile
w32tm /config /syncfromflags:manual /manualpeerlist:"0.windows.time.com 1.pool.ntp.org" >> $logFile

Deleting a scheduled task if required:

schtasks /Delete /TN "StartupPowerShell"

Running a scheduled task if to test:

schtasks /Run /tn "StartupPowerShell"
