You will have to ask Microsoft that question.  It's a Microsoft product.

There are two Windows builds of the reference implementation of ntpd; 
either one should give you much better synchronization than W32TIME. 
Ntpd will query its servers at intervals ranging between 64 seconds and 
1024 seconds.  The daemon adjusts the interval automatically to the best 
value for current conditions.

See http://norloff.org/ntp/ or http://www.meinberg.de/english/sw/ntp.htm 
  The latter version comes with a Windows installer.  I have not used 
either version and so can't tell you much about them except that either 
should perform better than W32TIME!!!!

If you decide to try one of these, your should plan on configuring at 
least four timeservers for best performance.

See http://ntp.isc.org/bin/view/Servers/WebHome for lists of publicly 
available time servers and "rules of engagement".
