Chronos is not a real NTP. On any reasonably modern Windows:
net time /setsntp:pool.ntp.org,0x8
or, in Au
net time /setsntp:au.pool.ntp.org,0x8
or, in NZ
net time /setsntp:nz.pool.ntp.org,0x8
The system event log will record some time related events.
If you know anything about Windows services, it's just about as easy to install a full blown
NTP as it is to install Chronos.
