Time-Service Warning ID 12

Question

In My Windows Server 2008 R2 OS in the Event Viewer there is an error pertains as Time-Service Warning ID 12 states-(Time Provider NtpClient: This machine is configured to use the domain hierarchy to determine its time source, but it is the AD PDC emulator
for the domain at the root of the forest, so there is no machine above it in the domain hierarchy to use as a time source. It is recommended that you either configure a reliable time service in the root domain, or manually configure the AD PDC to synchronize
with an external time source. Otherwise, this machine will function as the authoritative time source in the domain hierarchy. If an external time source is not configured or used for this computer, you may choose to disable the NtpClient.) What is this error?
And What is the remedy for this error?
