Timezone query

Hi

I've got a query about timezones and dates.

I'm in New Zealand and we finished "Daylight Savings" time last month. 
Issueing a "date" command from the shell returns:
Fri Apr  8 17:30:40 NZST 2005

To me this looks as if it thinks I'm in "NZ summer time". The time 
reported is actually correct but the timezone info appears to be off. 
I'm unsure as to whether I'm off by one hour or not.

I have /etc/localtime linked to /usr/share/zoneinfo/NZ and am running 
OpenNTPD which is serving time to all the machines on my network.
I don't have a TZ environment variable set.

Any idea where I should look for the problem, if indeed there is a 
problem ?
