I travel quite a bit worldwide and my Desire always manages to adjust to the new timezone within a few minutes of arriving and switching it on. However this is now not working. Have just travelled from London to Doha where it failed to reset, and now am in Australia where it has also failed to reset. I have had to make it think my home city is Sydney to get the time correct. I had not changed anything up until then and left automatic ticked under settings. Anyone know why this might be happening?
