Apple acknowledges that the latest firmware iOS 4.1 has a bug that will affect the device when Daylight Saving Time ends later this month. Initially this bug was reported by Apple Australia and reported to be set for correction in iOS 4.2.
Thankfully, there is a work-around for the bug. Just before midnight Saturday any alarm that is set to automatically repeat should be changed to "Never". After November 7th, you can set them back to repeat.
