The alarm goes off at times I haven't set on my iPhone5 (last year's). WTF?

I work shifts and I set it every week on a different shift pattern. I previously thought I set it to go off at the wrong time but it has definitely gone off at a time I didn't set. The time it went off, that alarm was in the off position with no days assigned to it at the time. It wasn't the shift I had last week either (it didn't get it mixed up/carry it over from last week). What can I do?

When will the iPhone 5s and 5c have price drops?

Do you think it would be worth it now to get the iPhone 5c 16gb? I'm in no rush to get the iPhone, but I don't want to wait till Christmas or any time around there.

What does iPhone 5s' 64-bit processor actually do?

*Please Read*

I don't want everyone just quickly responding with "It's pointless!"
I have heard people say before that this 64-bit chip is rather meaningless now but in the future it might mean something good. What exactly does that mean? I mean, you'd think Apple wouldn't advertise the fact that it has a 64-bit chip if it was completely and utterly useless!

So, what is 64-bit? What does it do? How will it benefit the iPhone? How long do we have to wait until we see a difference?
