Yep, it worked ie -

[TiVo [p0] ~]# ntpdate -v -b 132.163.4.103
oztivo ntpdate $Revision: 1.21 $
Our postcode is 03000. Found matching timezone Australia/Melbourne
Offset 39600 for timezone EST, daylight saving is 1
Connecting to time server 132.163.4.103
Setting the local time to Sun Feb 17 15:43:34 2008
[TiVo [p0] ~]#
And that is the correct post code and date/time.

Thoughts?
