I’ve found a workaround. Write the correct date and time in a batch file and run the batch file instead of the command processor.
Code:
#persistent
Tick0 = %A_TickCount%
Time0 = %A_Now%

SetTimer TimeCheck, 1000
return

TimeCheck:
   Transform SecTick, Round, (A_TickCount-Tick0)/1000
   SecPC = %A_Now%
   SecPC-= Time0,S      ; Time Difference in Seconds

   if (SecTick-SecPC < 2 && SecPC-SecTick < 2)
      Return

   Time0 += SecTick,S   ; Keep time as YYYYMMDDHH24MISS
   FormatTime Date, %Time0%, MM-dd-yyyy
   FormatTime Time, %Time0%, HH:mm:ss

   FileDelete ResetDateAndTime.bat
   FileAppend Date %Date%`nTime %Time%, ResetDateAndTime.bat
   runwait ResetDateAndTime.bat

   Tick0 = %A_TickCount%
   Time0 = %A_Now%

   MsgBox PC time has been changed!`nWe have just reset it for you.

Cool! It works. The key is to use cmd.exe (%COMSPEC%), not command.com. Who knew they are so different? Actually, the /C has to be used:
Code:
run %COMSPEC% /C time 11:00:00
otherwise a command window is left open.

So, with Garry’s help the time-change-prevention script is further simplified:
Code:
#persistent
Tick0 = %A_TickCount%
Time0 = %A_Now%

SetTimer TimeCheck, 1000
return

TimeCheck:
   Transform SecTick, Round, (A_TickCount-Tick0)/1000
   SecPC = %A_Now%
   SecPC-= Time0,S      ; Time Difference in Seconds

   if (SecTick-SecPC < 2 && SecPC-SecTick < 2)
      Return

   Time0 += SecTick,S   ; Keep time as YYYYMMDDHH24MISS
   FormatTime Date, %Time0%, MM-dd-yyyy
   FormatTime Time, %Time0%, HH:mm:ss

   runwait %COMSPEC% /C Date %Date%
   runwait %COMSPEC% /C Time %Time%

   Tick0 = %A_TickCount%
   Time0 = %A_Now%

   MsgBox PC time has been changed!`nWe have just reset it for you.
Return
To defeat it the user has to delete cmd.exe from the Windows directory. It is a system file, so Windows (2K, XP) replaces it immediately. There is a trick to remove it anyway: in a batch file delete it and rename another system file to cmd.exe, but it will cripple Windows. But in any case, temper resistant SW has to periodically check if there is a valid cmd.exe, and restore it if needed.
