Hi all,

This morning I received email from the (Australian) National Measurement 
Institute (NMI) notifying me that they are changing the IP address of 
their Melbourne NTP server shortly and it occurred to me that perhaps 
others weren't aware that the NMI operate national NTP servers with 
chime based from a caesium atomic clock located at NMI’s Lindfield 
laboratory. You must register your IP addresses with them in order to 
use them but more information is available at


and scroll down to "NTP Servers".

I'm not associated with NMI so if you have questions then ask them.
