Hi, I agree with JM and Ace, What i thought that you might consult with this engineer and finger out what's the reason that the third party application required? These are the global Group Policy settings and default values for the Windows Time service.

Please rate your experience Yes No. Any additional feedback? Caution Don't use the Net time command to configure or set a computer's clock time when the Windows Time service is running.
Note If you have a computer with multiple network adapters is multi-homed , you cannot enable the Windows Time service based on a network adapter. Important Windows Server has improved the time synchronization algorithms to align with RFC specifications. Note In this case, if you want to set the clock back slowly, you would also have to adjust the values of PhaseCorrectRate or UpdateInterval in the registry to make sure that the equation result is TRUE.
Note When you remove a Group Policy setting, Windows removes the corresponding entry from the policy area of the registry. Warning This information is provided as a reference for use in troubleshooting and validation. Note Some of the parameters in the registry are measured in clock ticks and some are measured in seconds. Ticks Property. Submit and view feedback for This product This page. View all page feedback.

Registers the Windows Time service to run as a service and adds its default configuration information to the registry. Unregisters the Windows Time service and removes all of its configuration information from the registry. Monitors the Windows Time service. Converts a Windows NT system time measured in 10 -7 -second intervals starting from 0h 1-Jan into a readable format.
Converts an NTP time measured in 2 -second intervals starting from 0h 1-Jan into a readable format. Tells a computer that it should resynchronize its clock as soon as possible, throwing out all accumulated error statistics. Displays a strip chart of the offset between this computer and another computer. Displays the values associated with a given registry key.
Displays the computer's Windows Time service information. Enables or disables the local computer Windows Time service private log. Controls whether this computer is marked as a reliable time server. A computer is not marked as reliable unless it is also marked as a time server.
Not a time server 0x Always time server 0x Automatic time server 0x Always-reliable time server 0x Automatic reliable time server The default value for domain members is Controls whether or not the chaining mechanism is disabled. If chaining is disabled set to 0 , a read-only domain controller RODC can synchronize with any domain controller, but hosts that do not have their passwords cached on the RODC will not be able to synchronize with the RODC.
Specifies the maximum amount of time that an entry can remain in the chaining table before the entry is considered to be expired. Expired entries may be removed when the next request or response is processed. The default value is 16 seconds. Controls the frequency at which an event that indicates the number of successful and unsuccessful chaining attempts is logged to the System log in Event Viewer.
The default is 30 minutes. Controls the maximum number of entries that are allowed in the chaining table. If the chaining table is full and no expired entries can be removed, any incoming requests are discarded.
The default value is entries. Controls the maximum number of entries that are allowed in the chaining table for a particular host. The default value is 4 entries. Specifies the smallest local clock adjustments that may be logged to the W32time service event log on the target computer. The default value is parts per million - PPM. Indicates the maximum number of seconds a system clock can nominally hold its accuracy without synchronizing with a time source.
If this period of time passes without W32time obtaining new samples from any of its input providers, W32time initiates a rediscovery of time sources. Default: 7, seconds. Controls which events that the time service logs. Time jump 0x2. Source change The default value on domain members is 2. The default value on stand-alone clients and servers is 2.
Controls the rate at which the clock is corrected. If this value is too small, the clock is unstable and overcorrects. If the value is too large, the clock takes a long time to synchronize.
The default value on domain members is 4. The default value on stand-alone clients and servers is 4. Controls the period of time for which spike detection is disabled in order to bring the local clock into synchronization quickly. It is highly recommended that you back up the registry as serious problems may occur if you modify the registry incorrectly, modifications to the registry are done at your own risk.
To configure the Windows Time service to use an external time source, click Start, Run and type regedit then click OK. In the right pane, right-click AnnounceFlags and click Modify. Network Time Protocol NTP is an Internet protocol used for the transfer of accurate time, providing time information along so that a precise time can be obtained. In the Edit DWORD box under base, click Decimal, under value data type the time in seconds you want to poll such as polls in one hour.
Now, to restart windows time service, click Start , Run or alternatively use the command prompt facility and type:. Source: Free Articles from ArticlesFactory. The default installation procedure automatically configures workstations and servers to sync to the controlling PDC. Only the PDC needs to be configured to synchronize to an external time reference. When modifying registry settings, it is always a good idea to backup the current settings beforehand.
You can revert back to previous settings if any problems occur with registry changes. Change the server type to NTP. Set announce flags. Specify the time sources.
