XP Time Synchronization

To control the number of seconds to wait between attempts to synchronize the
system clock to an time source on the Internet using the following Windows XP
registry hack:

Hive: HKEY_LOCAL_MACHINE

Key: SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient

Name: SpecialPollInterval

Type: REG_DWORD
Value: #secondsdesired default

Don't set it too low. Your PC clock doesn't drift that fast. Once a day is
good enough.

(default) will control which time server to use. The Servers key will have
entries for internet time servers. For example my system has (default)=2, value
1="time.windows.com" and value 2="time.nist.gov". Meaning my time is syncronized
from the nist.gov site. To control which time source to synchronize the system
clock with, use the following Windows XP registry hack:

Hive: HKEY_LOCAL_MACHINE

Key: SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers

Name: (Default)

Type: REG_SZ
Value: entry of
choice, 1-# time servers you have default

If you want to add a new time server, add a new value, in my example the next
value 3="thenewtimeserver.com"
