Atomic Clock Sync?

Been searching, and haven't found any free utilities to sync individual users to the atomic clocks. Anyone point me in the right direction?

    No need for a separate utilitiy. I believe that by default individual Windows PCs will synchronize with time.windows.com (which is sync'd to the global UTC servers). You could change this to another server (tick or tock.usno.navy.mil are popular) with a registry edit:

    Key:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
    Value:
    NtpServer
    Data:
    time.windows.com,0x1
    (or other servers separated by commas)

    Restart the Windows Time Service and watch the event viewer for any W32Time errors.

    Domain PCs will automatically sync with the authenticating domain controller, which will sync with the PDC emulator for the domain, which will sync with the server set in the registry key above.

    Thanks I will try this. We have a lot of stand alone laptops we need to sync so the users can punch in/out each day. Ive already found a hack to stop them from changing time on their individual machines, which is very helpful.

    Maybe you should try and do some research before you ask such questions, atomic clock, do you even know what a 1 or statum 2 is?

    [FONT=Courier New][SIZE=3]net time /querysntp[/SIZE][/FONT]
    
    will show the current settings on Windows.
    [FONT=Courier New][SIZE=3]net time /setsntp:<NTP SERVER>[/SIZE][/FONT]
    
    will set new ones. Check ntp.org for your region.

    On systems I maintain I use the following which querys all four ntp.org U.S. pools.
    [SIZE=3]net time /setsntp:"0.us.pool.ntp.org 1.us.pool.ntp.org
    2.us.pool.ntp.org 3.us.pool.ntp.org"[/SIZE]
    
    After setting this on the command line you can restart the time service via
    [FONT=Courier New][SIZE=3]net stop w32time && net start w32time[/SIZE][/FONT]

    Thanks for the net time commands. I have always set this by script and can never remember what the net commands are.
