Network Time Protocol

This syncs too infrequently for me. To increase the reduce the frequence that the NTP Client will poll your time server, go into regedit key:

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

and look at the SpecialPollInterval. This is the number of seconds between updates.

To change it to 24 hrs, use 86400 (this is 1 * 24 * 60 * 60). By default it is set to update once per week (604800).
