Stop users from manipulating the time

[PcExpert]

Hi all,

I've made a script that will block MSN at 20:00 but how to stop a user from changing the time, because if a user sets the time one hour back, then the script will allow msn again.

Thanks!

While 1 
    If WinExists('Date and Time Properties') then 
        WinClose('Date and Time Properties') 
    EndIf 
    Sleep(100) 
WEnd

If WinExists('Date and Time Properties') then 
    WinSetTrans('Date and Time Properties', '', 0) 
EndIf

This way is probably better

EDIT: Now I can't figure out how to show it! (Well, other then writing a script to do it)

Thanks! Is there also another way to do it. The way you mention works perfect, but if the user closes the program, then it wont check anymore. Is there maybe somethng in the registry that can be modified?

Write a function that has the AutoIt application check the system time every minute. If the AutoIt application checks the time and finds that significantly more time than a minute has gone by or time has gone backwards, have the AutoIt application query a web server for the time and then have it set the system clock to that time. Then have it use the web server's time as the correct time. This will fix the time that the user set incorrectly and will prevent the AutoIt script from even using the system clock's time if it suspects it has been tampered with.

Note: You could also have an intranet LAN server give the time if you are doing this for a business network.

This is a complicated fix, but I am trying to make it fool proof.

You could also go to (not sure about english names) controlpanel>"administration tools">"local securityprinciple" and then you remove the rights to change the clock for everyone except the administrator (assuming the users aren't admins or know how to change it)

Yes, this is a way of doing it. Just did it myself and this is the exact process as stated by TzarAlkex with some addition:

Go to Control Panel > "Administration Tools" > "Local Security Policy"

Once there expand the "Local Policies" tree. Then select "User Rights Assignment" and look in the list view area for "Change the system time".
