Windows Administrator shell command execution

[Harald Oehlmann]

On a stand-alone Windows 10 System, I want to set the system clock.

This aparently requires administrator privileges.

https://www.wikihow.com/Change-the-Computer-Time-and-Date-Using-the-Command-Prompt

The command "date" and "time" should be executed.

Is there any experience, how to do that from a TCL program?
The administrator prompt would be ok for me.

Thus, create a batch file with parameters and give them administrator
properties.
Then execute them with exec...

I will try.

Thanks for any idea,
Harald

Could this be done via TWAPI?

Thanks, Arjen, for the response.
I want to state, that the issue is not to hot at the moment.
I may care in a month or so.

Thank you all,
Harald

twapi::shell_execute -verb runas -path cmd.exe -params {/c time 04:49 pm}

Note user will get the elevation prompt.

To run a program as administator on windows 10 w/o
needing to respond to the UAC prompt, one can create a
task scheduler entry.

Only about 25 steps, but hey, this is windows :)

I use this technique to launch a tcl/twapi program to
run an easeus todo incremental image backup with 1
click whenever I get nervous about un-backed up work.

Dear Ashok,
that just works great, thank you !

Here is the extended solution to set time and date together:

twapi::shell_execute -verb runas -path cmd.exe -params {/c "time 09:46 &
date 3.3.2023" }

My appreciations to the encoding work !

Thanks again,
Harald
