Network Time Protocol (NTP) is used to keep hardware clocks in sync.
This syncs too infrequently for me. To increase the frequency 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).
