Change BlackBerry time zone automatically issue. you’ll find that BlackBerry time zone can’t change automatically. The automatic network time feature might be disabled because the Blackberry also contains a calendar full of entries containing various start/end times, and changing time zones automatically might cause confusion with some users if they are travelling. so we should change time zone manually. we should reset the time at Options > Date/Time. and I heard that there is an application called AutoTimeZone on App World which can change time zone automatically. but I can’t find it.maybe it just rumour.
