It is, but it is not simple to configure. Look in the list archives for
examples of conifguring the windows time service for use on public NTP
networks. Included there are links to Microsoft's detailed
documentation on the Windows Time Service.

What are your requirements? Just to keep better time? Why once every
1/2 hour?

Generally, you'll want to use a configuration command like this:

w32tm /config /manualpeerlist:"0.us.pool.ntp.org,0x8
1.us.pool.ntp.org,0x8 2.us.pool.ntp.org,0x8" /syncfromflags:MANUAL
/update

That ",0x8" after each server tells Windows Time Service to choose the
best synchronization interval itself, based on the performance of your
clock and/orn network connection.

Also, please note that the windows time service only makes event log
entries when a new time srouce is selected, plus an informational entry
once every X hours. It will not make a log entry for "small
corrections", even if they are more frequent. This logging behavior can
also be changed with registry entries or group policies (see Microsoft
documentation).,
