By default, the primary domain controller (PDC) emulator gets its time from the BIOS clock. In a network with a single DC, that DC automatically has this role.

The PDC emulator establishes the time and date settings for all computers within its domain. If the time is not accurately set in the PDC emulators BIOS, all computers in the domain have incorrect time and date settings.

To prevent this, you can synchronize the domain controller with an external time source such as the time servers provided by the National Institute of Standards and Technology (NIST). For a list of the names and IP addresses of NIST time servers for your area, see the National Institute of Standards and Technology (NIST) Internet Time Servers link on the Web Resources page at http://www.microsoft.com/windows/reskits/webresources.

To synchronize the domain controller with an external time source
Click Start, and then click Command Prompt.

In the Command Prompt window, type the following line, where peers is a comma-separated list of IP addresses of the appropriate time sources, and press ENTER:
w32tm /config /manualpeerlist: peers /syncfromflags:MANUAL
The time sources you choose depend on your time zone. For example, if your domain controller is located in the Pacific Time zone, this line might read:
w32tm /config /manualpeerlist:131.107.1.10 /syncfromflags:MANUAL
In this example, the IP address of the timeserver is used instead of the fully qualified domain name for security purposes.

Press ENTER. You should get a message that the command completed successfully.

Type w32tm /config /update

Press ENTER. You should get a message that the command completed successfully.
W32time uses a variable poll interval based on the quality of timesync with the server. On DCs, this interval defaults to between 64 and 1024 seconds.

To immediately synchronize with the external time server, type w32tm /resync and press ENTER. You should get a message that the command completed successfully.

Type Exit and press ENTER

Also this being your primary DC you should be a member of domain admins group to do the changes.
