Hi Steve,

The time issues of Freeview do not end with the absence of Timezone offsets.

All programme start times in the EPG from freeview are expressed as wall clock 
time in the system that would be applicabe at the start of the programme.

That means that 2 programmes could have started on the same channel at 2:00am 
on Sunday 1st April 2012 when the clocks wentback to end NZDT.

I can only guess that the Freeview / MHEG protocols send a clock change 
command whenever it is requied on a MyFreeview DVR device..

I have been working on my own version of a MHEG grabber and I have assummed 

	a) All times in the EPG are wall-clock time (subsequently confirmed by 
careful observation).

	b) At end of Daylight Savings, programmes that are due to end at a time 
between 2:00 and 3:00 then NZDT is used for the start time and NZST is used 
for the end time.  Potentially this means that a programme is recorded for 60 
mins to long  but least nothing is lost.
