Nokia :: Daylight Saving & Time Zone With Synchronising Calendar

I recently travelled to Melbourne from Perth with my fancy new N97, after successfully syncing my Outlook calendar etc from my laptop to the N97 using Ovi Suite (which I agree is not as good as the old PC Suite). Time zone change has caused me a few problems, as the automatic update of the time when I arrived in Melbourne didn't take daylight saving into account, so the alarm went off an hour late etc, and so I had to manually adjust the clock. Funny that now the world clock on my phone is out by an hour now that I have arrived back in Perth. So predictably, the calendar entries now that I'm back in Perth are an hour out.

Any easy ways of updating the world clock settings so that Perth (GMT+8hrs) actually reflects what the time is so that the calendar will sync? At the moment the N97's world clock states that Perth time is 0553hrs, but the time is actually 0653hrs. If I ask the phone to change to Perth as the current location, it asks whether to change phone time to match local time in selected location, which means that the clock continues to show the correct time, despite the world clock being incorrect. I think this is the problem anyway. Thoughts?
