Chatham Islands time

[Chris Carrier]

Some thoughts on the Chatham Islands time of time change.
 
The legal standard time of the Chathams is GMT+12:45, and they observed DST on
the same dates as New Zealand, which they are legally tied to.  When NZ was
making its time changes at 2:00 NZ time, the Chathams changed at 2:45 Chatham
time, which was the same time (14:00 GMT of the previous day in both places).
 
Since NZ just changed at 1:00, I would presume the change in the Chathams was
at 1:45.
