Not exactly. The guide data should represent which timezone it is from, so you 
can adjust accordingly. Using the (updated for perth) timezone info allows 
myth to know what adjustment needs to be made. On my system, the daylight 
savings changeover is automatic, and I don't have to fudge the guide data. 
The guide data might change to daylight savings too, or it might be in 
universal time..... Either way, as long as it correctly reports the time, and 
timezone, you can convert it to universal time, and/or local time. A lot of 
the guide data out there doesn't correctly report the timezone, so 
myths "auto" mode doesn't work, forcing you to specify the time offset.
