Apparently more than they have on the feature at present. With the change to Daylight Savings Time, my office has run amok with iPhone users that seemingly are unable to tame their phones into sounding their alarms at pre-set intervals.
What happened is that the phones seem to have sprung forward an hour as they were supposed to, but alarms were mysteriously moved back an hour. The result? Random alarms going off at random times and designers and developers unable to get to work on time.
My Android (HTC Hero) on the other hand has no issues with time. Google seems to have got that one right.
