Hi,

i need some small code to sync the WINDOWS TIME now....
CODE or this wich does not work IMEDIATLY.....

w32tm /config /manualpeerlist:time.windows.com /update


The time sync is needed so i can test for the correct time,
and shutdown the pc.
If a user adjust the windows clock.......... shit...... then the time
server needs to be synced.

whatever works......
i only need to sync the windowstime.....WITHOUT a delay...
whatever works........


code or command.......... whatever works.

thanks.

Assuming you have Windows configured to get its time from a time server (the default setting as far as I know)...

http://support.microsoft.com/kb/314054

To reset the local computers' time against the time server, run the following command on all the computers except the time server:

w32tm /resync /rediscover

I want to use it from c/c++

HIDEWINDOW("CMD") // NOT IMPORTANT.


system("w32tm /resync /rediscover");

on my system i get a error:
Sending resync command to local computer...
The computer did not resync because no time data was available.


I need this so my SERVICE.EXE can sneaky send time updates.
My program is a CYBER PARRENT control..... and i the users adjust the windows clock........
the program is useless so i am trying to find a way to sync the windows clock....


Thanks.

An alternative you could try is:

NET TIME /SET

Or implement your own NTP client (it's not too hard) and use http://www.pool.ntp.org/ to get the time.

You can use this library to get you started

http://www.hotscripts.com/listing/hs-ntp-c-source-library/

"HS NTP C Source Library

HS NTP is a software library in C (supplied with full source code) which implements the client side of Network Time Protocol (NTP) over UDP socket layer according to RFC1769 and RFC1305. HS NTP Library allows a user application to synchronise local system time to remote NTP server time. First user application calls HS NTP initialisation function supplying pointers to callback functions in user code for timer management and for reporting NTP events to user. To obtain time difference between local system and remote NTP server, the user application calls HsNtpGetTime function, specifying NTP server name or IP address and source UDP port to use. HS NTP library then resolves the server name, formats and sends NTP time request packet according to RFC1305 and RFC1769 standard. Once HS NTP has received NTP time reply from NTP server it analyses the reply and reports the resulting time difference to user application via callback function"

>> I am just looking for a simple solution
Well, I think we've ruled that out :)

Implementing your own ntp client (using the code above) is going to be relatively simple (since the hard work has already been done). The problem with the command line approach is it relies on the Windows time service being configured correctly. Since you are looking to implement this as a security feature you can't really rely on this. Secure and simple rarely go hand in hand I'm afraid.
