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:
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
