I think you've missed my point on this one Shay.
My point was: why didn't my clock roll back the second daylight
saving should have finished (03:00 WDT 25 Mar)? And secondly, why
does my time zone say WST instead of WDT?
Derek said that in his testing it too didn't roll back when it should
but did within an hour.
I repeated my test and left it for quite a while (> 2h) and it still
hadn't rolled back.
I'm aware of what you said about NTP (my sentence actually said the
same thing as you) and I had made a very similar comment on this list
to someone else previously.

PS On further testing just now and using the date -u command to check
for time differences from UTC, I see that If you set the clock to
anything past 02:00 on 25 Mar, it assumes that DS has ended. So to do
my test properly I assume I'd have to set the clock to 01:59, and
wait 61 mins instead of setting it to 02:59 and waiting 1 minute. So
I'll therefore conclude that the end of DS will work as it should.
But it would be nice if Apple displayed WDT when it should instead of
always WST.

Anyway, to check the end of the DS, I disabled NTP and set my
clock to 25 Mar 2007 02:59:50 and was hoping that in 10 secs the
time would be 02:00:00. Instead it just rolls over to 03:00:00.
I would have expected the DS zone changes to be independent of the
NTP activation.
Comments?
The Network Time Protocol (NTP) simply synchronises the computers
idea of what UTC (ie Greenwich Mean Time) is. Applying Timezone
changes to UTC to work out what the local computer's time is is
left to each individual computer's OS. Thus not being connected to
NTP shouldn't make any difference for purposes of testing the
daylight savings changeover.
