To add additional time servers, start the Registry Editor (regedit) and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers\
    1. Right-click an empty space in the right pane and select New > String Value
    2. Name the new value with a number one higher than the last (so the first you add will have the value 3, since 1 and 2 are given)
    3. Double-click this new value, and enter the hostname as it's Value data
    4. Close the registry editor
Additional information on public time servers can be found at the following sites:
Public NTP Time Servers
USNO NTP NETWORK TIME SERVERS

To change internet time synchronization schedule, open your registry and find or create the SpecialPollInterval key located here:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient\

Create or modify "SpecialPollInterval" as a DWORD DECIMAL based key in seconds.

Here are a few common intervals:
One Hour=3600
Twice a Day=43200
Daily=86400
Weekly=604800

Exit your registry, you may need to restart or log out of Windows for the change to take effect.
