You try the GetSystenTime function.

Code:

 
The GetSystemTime function retrieves the current system date and time. The system time is expressed in Coordinated Universal Time (UTC). 

VOID GetSystemTime(

    LPSYSTEMTIME lpSystemTime    // address of system time structure  
   );      
 

Parameters

lpSystemTime

Points to a SYSTEMTIME structure to receive the current system date and time. 

 

Return Values

This function does not return a value.

Hi Logic,

this code works for me:

;***------------model----------------------------------------------***
format PE console

include '%include%\WIN32A.INC'
;***------------end model------------------------------------------***

_TITLE equ "Local Time"
_NAME equ "LocTime"

Main:
stdcall [GetStdHandle], STD_OUTPUT_HANDLE
mov [StdOut], eax
cmp eax, INVALID_HANDLE_VALUE
jz Exit
Get_Time:
stdcall [GetLocalTime], Time
call Format_Time
Write:
stdcall [WriteFile], [StdOut], Msg, Msg._size, Msg.Len, 0
Exit:
stdcall [ExitProcess], 0

;***-------------------------[Subroutine]--------------------------***
Format_Time:
mov ax, [Time.wDay]
mov edi, Msg.Date_S + 1
call .ascii

mov ax, [Time.wMonth]

mov ax, [Time.wSecond]
mov edi, Msg.Time_S + 7
call .ascii
ret

.ascii:

Hey, I recognize that code. Razz

Glad that you're getting some use out of it

please, post an example for me?
how could i SetSystemTime!? set to like 0101200100000000

Code:

 ; why not work!?
include '%fasm%\win32ax.inc'

section '.code' code readable executable
start:

        invoke SetSystemTime,lpSystemTime
        invoke ExitProcess,0


section '.data' data readable writeable

lpSystemTime SYSTEMTIME 1,1,1,1,1,1,1,1

data import

        library kernel32,'KERNEL32.DLL'
        import kernel32,ExitProcess,'ExitProcess',\
        SetSystemTime,'SetSystemTime'

end data

From the Win32 FM

Quote:

typedef struct _SYSTEMTIME { // st
WORD wYear;
WORD wMonth;
WORD wDayOfWeek;
WORD wDay;
WORD wHour;
WORD wMinute;
WORD wSecond;
WORD wMilliseconds;
} SYSTEMTIME;

So like this maybe?

Code:

lpSystemTime SYSTEMTIME 2001,1,1,1,0,0,0,0

really work it now!

das ist fantastisch! - it's only this 1,1,1,1,1,1,1,1 synops problem!?

thanks!!! cool!

I think about this before
"Remarks:

The SetLocalTime function enables the SE_SYSTEMTIME_NAME privilege before changing the local time"

It's sure? Smile

Why need?

Remember that in later versions of Windows, setting the time requires SeSystemtimePrivilege. You may have to enable this privilege before you code can successfully set the time.

Call this first.

Code:

struc LUID_AND_ATTRIBUTES {
      .Luid           dq      ?
   .Attributes     dd      ?
}

TOKEN_ADJUST_PRIVILEGES      =0x0020
SE_PRIVILEGE_ENABLED =2

.data

 hToken  dd      ?
   tokens  dd      ?
   luid    LUID_AND_ATTRIBUTES

.code

get_time_privileges:
    invoke  GetCurrentProcess
   invoke  OpenProcessToken,eax,TOKEN_ADJUST_PRIVILEGES,addr hToken
    test    eax,eax
     jz      .proces_token_failure
       invoke  LookupPrivilegeValue,0,'SeSystemtimePrivilege',addr luid.Luid
     test    eax,eax
     jz      .lookup_privilege_failure
   mov     [tokens],1
  mov     [luid.Attributes],SE_PRIVILEGE_ENABLED
      invoke  AdjustTokenPrivileges,[hToken],0,addr tokens,0,0,0
  test    eax,eax
     jz      .adjust_privileges_failure
  xor     eax,eax
     ret
    .proces_token_failure:
       mov     eax,-1
      ret
    .lookup_privilege_failure:
   mov     eax,-2
      ret
    .adjust_privileges_failure:
  mov     eax,-3
      ret
