Error in clock world time database
 

Hi all, I bought a 770 a few months ago due to them being ridiculously cheap at Expansys. I'm very happy with it although it's mostly being used as an alarm clock at the moment. I've found an error in the clock though: I have home time set to London, UK with GMT+BST and destination time set to Santiago, Chile. The clock gives Santiago's time as London - 1, whereas it's currently -5. Are the time zone details editable? The only reference I can find to it suggests that it might not be a good idea to fiddle with the config files.
