Changing the NTP update interval in Windows

Default is 604800 seconds (7 days), which is way way too long. On my machine, I'm getting clock skews of close to a minute as a result, and that's not acceptable when you're swapping files around for compilation for instance.

To set this value to a more reasonable interval, you need to update the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\W32Time\TimeProviders\NtpClient\SpecialPollInterval
